[0004] Field of the Disclosure
[0004] The present disclosure relates to novel enzyme activity domains, cell wall binding domains, and cell wall hydrolases having activity against Cutibacterium acnes. The present disclosure also relates to compositions containing these recombinant domains and proteins, and methods of treating conditions associated with Cutibacterium acnes.
Background Art
[0005] Background
[0005] Acne vulgaris is a chronic inflammatory disease of the follicular sebaceous gland units, affecting up to 50 million people annually in the United States. Acne can have significant adverse effects on psychosocial functioning, such as increased anxiety, decreased self-esteem, depression, academic failure, and suicidal ideation. The anaerobic Gram-positive bacterium Cutibacterium acnes (formerly known as Propionibacterium acnes) plays a significant role in the development of acne. C. acnes is the most common species in the follicular sebaceous gland units, and in contrast to previous models that linked acne to C. acnes proliferation, metagenomic analysis now shows that the relative abundance of C. acnes is similar between healthy skin and acne-prone skin. Instead, it is now understood that acne development is associated with a loss of C. acnes phylogenetic diversity. C. acnes strains are classified into six major phylogenetic types based on their genome sequence: IA1, IA2, IB, IC, II, and III. Numerous studies have linked acne to a higher relative abundance of phylogenetic type IA1. This relative abundance is specifically reduced in non-phylogenetic IA1 strains, which is thought to induce innate immune stimulation and acne development. Antibiotics continue to play a central role in the treatment of acne. First-line combination therapy includes topical antibiotics for mild to moderate acne and systemic oral antibiotics for moderate to severe acne. Although effective, high levels of antibiotic use, especially systemic oral antibiotics, present challenges. Firstly, there may be unintended adverse effects on the gut and skin microbiome, such as changes in microbial composition, reduced microbial diversity, and altered functional attributes. Secondly, the overuse of antibiotics exacerbates antibiotic resistance, which poses an imminent public health threat. Therefore, there is a strong need for novel antimicrobial agents that can target C. acnes and provide microbiome-friendly alternatives to standard antibiotics.
[0006]
[0006] Endorcine is a phage-encoded bacterial cell wall-degrading enzyme that catalyzes the rapid and selective death of bacteria in the skin microbiome. Endorcine is typically expressed in the later stages of the phage lysis cycle. Endorcine binds to the host bacterial cell wall and rapidly degrades it, causing the cell to rupture and releasing mature viral particles. Endorcine can lyse its congeners even within biofilms, and bacteria have difficulty evolving resistance to endolysin because they have difficulty altering their peptidoglycans without harmful effects. However, all previous attempts to develop endolysin targeting C. acnes have faced significant challenges.
[0007]
[0007] Firstly, the diversity of known C. acnes phage / endolysin is extremely low. Through comprehensive efforts to isolate and sequence C. acnes phage diversity, all C. acnes phages isolated to date have been found to be very similar to one another, with little variation in gene content between genomes. The nucleotide sequence identity between any pair of C. acnes phage genomes is in the range of 85-100% (Liu et al., ISME J. 2015 Sep; 9(9): 2078-2093; Marinelli et al., mBio. 2012 Sep-Oct; 3(5): e00279-12). These genomes contain only a single, highly conserved endolysin, which significantly limits the amount of natural diversity available for endolysin development (e.g., the protein sequence with NCBI accession ID: YP_006907103.1, hereafter referred to as "CaLys1"). In contrast, endolysins targeting Staphylococcus sp. species can be classified into at least 27 subgroups (Oliveira et al., BMC Genomics. 2019 May 9; 20(1):357).
[0008]
[0008] The second challenge is that attempts to characterize CaLys1 and its closely related homologs from C. acnes phage face problems involving low solubility and low activity. Several groups have attempted to express CaLys1 and its closely related homologs by recombination and have found that the proteins are insoluble. Resolubilizing the proteins requires labor-intensive methods such as the use of urea gradients, which is not a commercially viable approach. In addition, this endolysin exhibits low activity in activity assays using high concentrations (e.g., 100 mg / mL) of the protein (see, for example, International Publication No. 2021 / 175606; Varotsou et al., Int J Mol Sci. 2023 May 10; 24(10):8523). [Overview of the project] [Problems that the invention aims to solve]
[0009]
[0009] Therefore, there is a strong unmet need for novel endolysins (and, more generally, bacterial cell wall hydrolases) that have improved properties compared to the currently known CaLys1 family and can selectively target C. acnes. [Means for solving the problem]

[0022] Detailed explanation
[0048] All publications, patents, and patent applications (including all drawings and annexes) are incorporated herein by reference to the same extent as each individual publication or patent application was specifically and individually indicated to be incorporated by reference.
[0023]
[0049] The following description contains information that may be useful in understanding this disclosure. This does not constitute an endorsement that any information provided herein is prior art, nor does it endorse any publication specifically or implicitly referenced as prior art.
[0024] definition
[0050] The terms “a” or “an” refer to one or more entities, that is, they can refer to multiple entities. Therefore, the terms “a,” “an,” “one or more,” and “at least one” are used synonymously in this specification. In addition, a reference to “one element” using the indefinite article “a” or “an” does not exclude the possibility that multiple elements exist, unless the context explicitly requires that only one element exists.
[0025]
[0051] Throughout this application, the term “approximately” is used to indicate that a value includes inherent variations in the error of the apparatus or method used to determine that value, or variations present between the samples being measured. Unless otherwise stated or otherwise evident from the context, the term “approximately” means within plus or minus 10 percent of the reported value (except where such a value is greater than 100% of the possible value or less than 0%). When used in conjunction with a range or set of values, the term “approximately” applies to each of the endpoints of the range or the values enumerated in the set, unless otherwise indicated. As used in this application, the terms “approximately” and “about” are used interchangeably.
[0026]
[0052] Unless otherwise indicated, all figures used in this specification and in the claims to represent quantities, ratios, and numerical characteristics of components, reaction conditions, etc., should be understood to be intended in all cases to be modifiable with the term "approximately".
[0027]
[0053] As used herein, the term “cell wall hydrolase” or “CWH” refers to a bacterial cell wall hydrolase, which is an enzyme that degrades peptidoglycan in the bacterial cell wall by cleaving the bonds in the peptidoglycan chain and side chain branches. Cell wall hydrolases can have various domain structures. A CWH includes an “enzyme-active domain” or “EAD,” which is a domain involved in the degradation of peptidoglycan. In some embodiments, the EAD has glycosidase activity, amidase activity, and / or peptidase activity. In some embodiments, a CWH includes a “cell wall-binding domain” or “CBD,” which is a domain that binds to the bacterial cell wall.
[0028]
[0054] The term "natural" protein is used to refer to proteins that exist naturally and have not undergone any artificial modification or recombination.
[0029]
[0055] The term “recombinant” is used herein to describe nucleic acids, proteins, vectors, and host cells in configurations that do not exist in nature or are not found in nature in relation to nucleic acids. Thus, “recombinant protein” refers to a protein that does not exist in nature. In some embodiments, recombinant protein refers to a chimeric protein, as used herein. In some embodiments, recombinant protein refers to the expression product of either the EAD or CBD sequence of this disclosure alone, or an expression product within a protein that does not exist in nature. For example, this disclosure assumes a recombinant EAD or CBD sequence of this disclosure fused to any protein tag, such as 6×His.
[0030]
[0056] As used herein, “heterogeneous” refers to any genetic material that is artificially introduced into a non-natural context. For example, a heterogeneous domain refers to a domain (e.g., EAD or CBD) that is artificially introduced into a recombinant protein sequence, and the resulting recombinant protein sequence is non-natural. Two polypeptide sequences or domains are heterogeneous if they originate from different natural polypeptide sequences or proteins. For example, in some embodiments, CBD and EAD are heterogeneous if they originate from different natural proteins.
[0031]
[0057] As used herein, “chimeric protein” is any recombinant protein comprising two or more heterogeneous domains (e.g., EAD and / or CBD).
[0032]
[0058] As used herein, a protein “domain” is a functional and / or structural subunit within a protein. In some embodiments, these are involved in specific functions or interactions and contribute to the overall role of the protein. Protein domains are the fundamental units of protein structure, folding, function, evolution, and design. See, for example, Wang et al., “Protein domain identification methods and online resources,” Comput Struct Biotechnol J 2021; 19:1145-1153 (incorporated herein by reference).
[0033]
[0059] As used herein, “chimeric cell wall hydrolase” or “chimeric CWH” is a chimeric protein that acts as a cell wall hydrolase and contains at least one heterologous domain (e.g., heterologous EAD or CBD) compared to a native CWH sequence. In some embodiments, chimeric CWH refers herein to a recombinant protein containing two heterologous CWH domains (e.g., EAD and CBD).
[0034]
[0060] As used herein, “activity” refers to the ability of a chimeric protein to inhibit the proliferation of cells derived from the species Cutibacterium acnes and / or to lyse these cells. The term “active against” refers, as used herein in relation to the target species of Cutibacterium acnes, to a chimeric protein of the disclosure (e.g., CWH) that is capable of inhibiting the proliferation of cells belonging to this target species of Cutibacterium acnes and / or lysing these cells. Activity can be calculated in various ways depending on the assay performed. In some embodiments, the level of activity is indicated based on the minimum inhibitory concentration ("MIC"), for example, based on the minimum concentration of protein required to prevent the proliferation of the target Cutibacterium acnes species in an MIS assay. In some embodiments, the level of activity is indicated based on turbidity reduction, for example, the activity is -ΔOD 600 It is calculated as / min / (mg of enzyme). In some embodiments, activity is shown based on the reduction of viable bacterial cells in the culture after an incubation period with the protein (e.g., 2 hours).
[0035]
[0061] In relation to anti-Cutibacterium acnes activity, the terms “selective” and “selectivity,” as used herein, refer to the property of a Cutibacterium acnes to exhibit higher activity against one target species compared to another species of Cutibacterium acnes. Selectivity may be calculated by comparing the reciprocal of the MIC of the chimeric protein against the first species with the MIC of the protein against the second species. In some embodiments, selectivity is determined based on relative activity in a turbidity reduction assay.
[0036]
[0062] As used herein, the term “sequence identity” refers to the degree to which two optimally aligned polynucleotide or polypeptide sequences remain invariant throughout the entire window of residue (e.g., nucleotide or amino acid) alignment. The “identity fraction” of the aligned segments of the test sequence and the reference sequence is the number of identical residues shared by the two aligned sequences divided by the total number of residues in the reference sequence segment (i.e., the entire reference sequence or a smaller defined portion of the reference sequence). The “identity percentage” is the identity fraction multiplied by 100. Sequence comparisons for determining the identity percentage can be achieved by many well-known methods, for example, by using mathematical algorithms (e.g., those in the BLAST suite of sequence analysis programs). Unless otherwise stated, the term “sequence identity” in the claims refers to sequence identity as calculated using MUSCLE (www.ebi.ac.uk / Tools / msa / muscle / ) with default parameters.
[0037]
[0063] As used herein, the terms “CW_7 cell wall-binding domain” or “CW_7 CBD” refer to a cell wall-binding domain comprising one or more CW_7 sequences. In some embodiments, the CW_7 CBD comprises, essentially comprises, or consists of CW_7 sequences.
[0038]
[0064] The term "including all ranges and subranges between them" or its equivalent is used herein to indicate the intent that any disclosure of any range or set of possible values also essentially discloses all ranges and subranges encompassed by the disclosed highest and lowest values. This term includes the entire range from the disclosed highest to the lowest values, as well as subranges from any two or more disclosed points. This term is also intended to disclose, to one decimal place, any subranges (including between any two points explicitly listed in the document) that are encompassed within the range of the disclosed highest and lowest values. Thus, the disclosure of the values 0, 5, 10, 15, and 20 (including all ranges and subranges between them) should be interpreted as including the ranges 0 to 20, 0 to 5 or 5 to 15, and 2 to 16 or 3.1 to 19.8, etc.
[0039]
[0065] Unless otherwise indicated, all figures used herein to represent quantities, ratios, and numerical characteristics of components, reaction conditions, etc., should be understood to be intended in all cases to be modifiable with the term "including all ranges and partial ranges between them."
[0040] overview
[0066] This disclosure provides novel enzyme-active domains (EADs), truncated enzymes, cell wall-binding domains (CBDs), and chimeric cell wall hydrolases (CWHs) exhibiting binding and / or enzymatic activity to Cutibacterium acnes. Also provided herein are compositions comprising the EADs, truncated enzymes, CBDs, and chimeric CWHs, and the use of these compositions in targeting Cutibacterium acnes and treating conditions associated with Cutibacterium acnes.
[0041]
[0067] CWHs are enzymes that degrade bacterial peptidoglycans by cleaving bonds in the peptidoglycan chain and side chain branches. CWH-mediated degradation of the peptidoglycan cell wall can lead to rapid lysis of bacterial cells due to their inability to resist internal turgor pressure. One advantage of using CWHs to treat conditions associated with Cutibacterium acnes is their high specificity. CWHs (e.g., Gram-positive endolysin) possess one or more cell wall-binding domains that bind to specific epitopes within the target cell wall. Because the composition and structure of peptidoglycan cell walls can vary significantly among bacterial species, CWHs often exhibit lysis specificity down to the genus, species, and even subspecies level. In active acne, C. acnes lineage diversity is reduced, and consequently, extensive removal of endogenous C. acnes can promote the re-establishment of lineage diversity. CWHs also offer a more direct and stable mechanism of action compared to phage therapy, another proposed antibiotic alternative.
[0042]
[0068] As demonstrated in the examples herein, this disclosure provides novel and highly effective EADs, truncated enzymes, CBDs, and chimeric CWHs exhibiting high lytic activity and / or Cutibacterium acnes species specificity. In some embodiments, the chimeric CWHs consist of domains derived from parent proteins and possessing superior properties to any of these parent proteins. In some embodiments, the CWHs herein bind to highly specific epitopes in target cell walls. In some embodiments, the CWHs herein have lytic activity down to a single species or a group of related species. Due to these properties, in some embodiments, the CWHs herein act as highly specific skin microbiome modifiers. For example, in some embodiments, the CWHs herein exhibit remarkably low activity against healthy symbiotic bacteria but are capable of specifically killing or modulating the diversity of Cutibacterium acnes.

[0166] Characteristics of the compositions disclosed herein
[0153] This disclosure provides chimeric proteins and compositions comprising these chimeric proteins. These compositions have properties beneficial for therapeutic use against the target Cutibacterium acnes.
[0167]
[0154] In addition to selectivity issues, previous CWHs and endolysins known in the art have properties that make them unsuitable for therapeutic indications (e.g., topical application). For example, previously characterized CWHs have problems with weak activity, low thermal stability, low solubility, and / or narrow or inappropriate pH ranges.
[0168]
[0155] This disclosure provides chimeric CWH having beneficial characteristics (e.g., high anti-Cutibacterium acnes activity, Cutibacterium acnes species specificity, thermal stability, solubility, and a broader or more preferred pH range).
[0169] Anti-Cutibacterium acnes activity
[0156] In some embodiments, the compositions of the present disclosure are active against the species Cutibacterium acnes. In some embodiments, the compositions of the present disclosure have activity against Cutibacterium acnes, and the degree of this activity is determined based on the minimum inhibitory concentration (MIC) for this target species. In some embodiments, the MIC is 100, 90, 80, 70, 60, 50, 40, 30, 20, or less than 10 μg / mL. In some embodiments, the MIC is 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, or less than 1 μg / mL.

[0172] Selectivity
[0159] The inventors have found that the exemplary novel chimeric organisms disclosed herein exhibit remarkable selective activity against Cutibacterium acnes more than other bacterial species. As is known in the art, the only CWH (CaLys1) previously known in the art to exhibit lytic activity against C. acnes also exhibits similar lytic activity against other bacterial strains, which is highly undesirable for topical skin microbiome applications. In contrast, the exemplary chimeric CWH of this disclosure is capable of distinguishing C. acnes from symbiotic skin bacteria.
[0173]
[0160] In some embodiments, the recombinant proteins of the Disclosure exhibit specificity to Cutibacterium acnes more than other species. In some embodiments, the recombinant proteins of the Disclosure exhibit specificity to Cutibacterium acnes more than symbiotic bacterial species. In some embodiments, the recombinant proteins of the Disclosure exhibit specificity to Cutibacterium acnes more than Corynebacterium xerosis, Corynebacterium striatum, and / or Staphylococcus epidermidis.
[0174]
[0161] In some embodiments, the recombinant proteins of the Disclosure have a selectivity of at least 2, 3, 4, 5, 6, 7, 8, 9, or 10 times.

In some embodiments, the compositions are suitable for use as a broad-spectrum therapeutic agent.
[0176] thermal stability
[0163] The inventors of this disclosure have also found, surprisingly, that some of the novel chimeric CWHs of this disclosure exhibit desirable high thermal stability.
[0177]
[0164] In some embodiments, the compositions of the present disclosure exhibit thermal stability at temperatures up to 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, or 60°C (including all values and ranges between these). In some embodiments, the compositions of the present disclosure exhibit thermal stability at temperatures of at least 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, or 60°C (including all values and ranges between these).
[0178]
[0165] As used herein, thermal stability at a given temperature refers to the ability to maintain an activity level at that temperature or the ability to maintain an activity level after exposure of a protein to that temperature. In some embodiments, thermal stability at a given temperature is measured after exposure to that temperature over a period of time. In some embodiments, thermal stability is determined based on experiments that test activity at a temperature or after exposure to a given temperature over a period of time (e.g., showing a measurable reduction in target bacterial density at or after exposure to that temperature). Thus, in some embodiments, an EAD, CBD, or chimeric protein is considered thermally stable at a temperature if it still exhibits measurable activity at a temperature or after exposure to a temperature. In some embodiments, an EAD, CBD, or recombinant chimeric protein is considered thermally stable at a critical temperature if it still exhibits measurable activity at its intended use temperature after exposure to the critical temperature (e.g., activity tested after the protein is exposed to this critical temperature for 30 minutes). In some embodiments, thermal stability after exposure to a given temperature is determined based on an assay performed at room temperature. In some embodiments, thermal stability after exposure to a given temperature is determined based on an assay that measures activity. In some embodiments, this assay is a turbidity reduction assay.
[0179]
[0166] In the context of comparing two proteins (e.g., two EADs, two CBDs, or two chimeric CWHs), one protein may be considered more thermally stable at a given temperature than the other if it exhibits higher absolute activity at that temperature or after exposure to that temperature (e.g., resulting in a greater reduction in microbial density over a measured period of time). In other embodiments, one protein may be considered more thermally stable at a given temperature than the other if it exhibits higher relative activity at that temperature or after exposure to that temperature (e.g., if this protein exhibits a smaller reduction in activity after exposure to that temperature compared to a relative reduction in activity of another protein after exposure to that temperature).
[0180]
[0167] In some embodiments, thermal stability at a given temperature is determined based on the ability to maintain activity after exposure to this temperature for 10, 20, 30, 40, 50, or 60 minutes (including all values and ranges in between). In some embodiments, thermal stability at a given temperature is determined after exposure to this temperature for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours (including all values and ranges in between). In some embodiments, thermal stability at a given temperature is determined after exposure to this temperature for 1, 2, 3, 4, 5, 6, or 7 days (including all values and ranges in between). In some embodiments, thermal stability at a given temperature is determined after exposure to this temperature for 1, 2, 3, or 4 weeks (including all values and ranges in between). In some embodiments, thermal stability at a given temperature is determined after exposure to this temperature for 1, 2, 3, 4, 5, or 6 months (including all values and ranges in between).
[0181]
[0168] In some embodiments, the thermal stability is measured based on a test of the activity after maintaining the composition at a given temperature for a period of time (e.g., several weeks or months). In some embodiments, the thermal stability is determined based on the activity retained after two months at a given temperature.
[0182]
[0169] In some embodiments, the compositions herein are thermally stable at 45 °C for at least four weeks. In some embodiments, the compositions herein are thermally stable at 45 °C for at least two months. In some embodiments, the compositions herein are thermally stable at 50 °C for at least two months.
[0183]
[0170] In some embodiments, the compositions herein are considered to be thermally stable or storable at room temperature if they retain at least 10, 20, 30, 40, 50, 60, 70, 80, or 90% (including all values and ranges therebetween) of their original activity at room temperature after exposure to a temperature of 45 °C for four weeks.
[0184] pH range
[0171] In some embodiments, the compositions herein are stable within a range of pH values. A composition (e.g., a chimeric protein) is considered stable at a given pH level if it exhibits activity at that pH level. In some embodiments, pH stability at various pH values is determined based on activity assays performed at various pH values. For example, in some embodiments, pH stability is determined by incubating the composition of the Disclosure (e.g., a chimeric protein) with target bacterial cells at various pH levels (e.g., in a turbidity reduction assay).

[Examples]
[0208] Examples
[0209] [Table 40]
[0210] [Table 41]
[0211] [Table 42]
[0212] I. Examples 1-4: Novel Endorphins of the genus Cutibacterium Example 1: Identification of novel CLC1 family endolysins, including amidasemain, in species of the genus Cutibacterium.
[0195] Previous attempts to identify endolysins that target C. acnes have focused on exploring the genomes of C. acnes strains, including C. acnes phages or prophages. However, this approach has only identified a single, well-conserved endolysin, as exemplified by protein sequence NCBI accession ID: YP_006907103.1 (referred to as CaLys1 in this application) (SEQ ID NO: 72).
[0213]
[0196] To identify novel endolysins targeting C. acnes, bioinformatics analyses were performed on a broader range of Cutibacterium species. While we do not wish to be bound by any particular theory, it is hypothesized that putative endolysins and cell wall hydrolases were found within the genomes of a broader range of Cutibacterium sp. species, and that phages infecting a broader range of Cutibacterium sp. species may also possess activity against C. acnes.
[0214]
[0197] These genomes were bioinformatics-analyzed for proteins containing the N-acetylmuramoyl-L-alanine amidase domain (PFAM:amidase_2), which is commonly found in endolysin across a wide range of bacteria, including the CaLys1 family. This search identified a novel family of amidases found in many Cutibacterium sp. species, such as C. avidum, C. granulosum, and C. porci, including 19 proteins which the inventors have named CLC1 to CLC19 (all referred to in this application as the "CLC1 family" amidases). The full-length amino acid sequences of CLC1 to CLC19 are included in SEQ ID NOs: 1 to 19, respectively. These amidases show similarities to the CaLys1 endolysin family (approximately 70% amino acid identity), but they form a distinct phylogenetic group from the CaLys1 family found in C. acnes phage / prophage (Figure 1A). Table 9 lists the GenBank ID numbers of the non-CLC1 family branches of the phylogenetic tree shown in Figure 1A. Phylogenetic comparison of only the amidase EADs (SEQ ID NOs. 20-36) of these proteins also confirmed that the amidase EADs of the CLC1 family are different from those of the CaLys1 family (Figure 1B). Table 10 lists the GenBank ID numbers and amino acid regions of the EADs of the non-CLC family branches of the phylogenetic tree shown in Figure 1B. Using multiple sequence alignment tools (Clustal Omega and EMBOSS Cons, see Madeira et al., Nucleic Acids Research 2024 Jul; 52(W1): W521-W525), we also determined that the EADs of the CLC1 family share a significant core of conserved residues (SEQ ID NO: 2939). Figure 27 shows the results of further motif analysis identifying conserved motifs in the EADs of the CLC1 family.
[0215] [Table 43]
[0216] [Table 44]
[0217] [Table 45]
[0218] [Table 46]
[0219] [Table 47]
[0220] Example 2: The CLC1 protein exhibits high solubility and significant anti-C. acnes lytic activity.
[0198] To test whether the putative endolysin CLC1 family possesses lytic activity against C. acnes, CLC1 was cloned into an inducible expression plasmid, and this protein was expressed in BL21 E. coli cells. A 6×His tag was added to this protein during these cloning steps. The cell lysates were then tested for activity in a clearing assay. The activity was tested using cell lysates. Briefly, C. acnes cells were embedded in soft agar to create an opaque plate. Candidate enzymes (either purified or derived from E. coli lysates) could be spotted onto this plate, and if the enzyme possessed anti-C. acnes activity, clearing / halo would occur. In this halo assay, clearing / halo was observed when lysates derived from BL21 E. coli cells expressing CLC1 were spotted, indicating anti-C. acnes activity (Figure 2).
[0221]
[0199] Importantly, the observed anti-C. acnes activity by CLC1 did not require any additional steps to resolubilize the protein. In contrast, lysates derived from BL21 cells expressing CaLys1 showed no clearing in this halo assay, which is consistent with previous reports that the CaLys1 protein is primarily insoluble (and therefore inactive) when expressed in Escherichia coli without further manipulation.
[0222]
[0200] To further clarify the activity characteristics of CLC1, CLC1 was purified from cell lysates using a 6×His tag and then tested in a turbidity reduction assay. In this assay, C. acnes cells were subjected to an OD of approximately 1.0. 600 The solution was resuspended and then tested with the purified enzyme. If this enzyme has C. acnes soluble activity, then OD 600The activity level decreased over time. This result confirmed that CLC1 possesses anti-C. acnes activity (Figure 3). In particular, CLC1 exhibited activity in a lower concentration range (6 μg / mL to 24 μg / mL) compared to that reported for CaLys1 (100 μg / mL). Furthermore, the CLC1 protein remained soluble after purification using a 6xHis tag. Therefore, CLC1 represents a novel endolysin that is solublely expressed in Escherichia coli (E. coli) and possesses lytic activity against C. acnes.
[0223] Example 3: CLC1 truncation exhibits improved solubility and solubility activity compared to the full-length protein.
[0201] Using SMART and CD-Search, we identified the bioinformatically predicted protein domains in the CLC1 family enzymes. Using these tools, we found that most members of the CLC1 family have an N-terminal amidase domain (EAD) followed by a C-terminal region of approximately 100 amino acids that does not contain the predicted protein domain. The exception is CLC15, which is predicted to have a longer repeating domain of unknown function.
[0224]
[0202] Despite the absence of all predicted protein domains, this C-terminal region is conserved among members of the CLC1 family and in CaLys1, suggesting that this C-terminal region may have several biological functions. To evaluate the effect of this C-terminal domain on CLC1 activity, we generated a truncated form of CLC1 lacking 85 amino acids at the C-terminus ("CLC1-truncation"). This protein was expressed in BL21 Escherichia coli (E. coli), purified, and tested using a turbidity reduction assay. Surprisingly, we found that CLC1-truncation increased solubility compared to full-length CLC1, as evidenced by the significantly higher yield of soluble protein after expression in E. coli. In addition, CLC1-truncation was found to be significantly more active than full-length CLC1 in a turbidity reduction assay measuring lytic activity against C. acnes (Figure 4). These data indicate that removing the C-terminal portion of the CLC1 protein has a positive effect on both solubility and activity, resulting in a more stable protein with much stronger lytic activity against C. acnes.
[0225] Example 4: Solubility and activity can also be improved by removing other CLC1 family proteins and the C-terminal region of CaLys1.
[0203] Full-length CLC2 and CLC3, when purified, exhibited relatively weak C. acnes lytic activity and lower soluble protein yields compared to other CLC proteins. The inventors removed approximately 85 amino acids from the C-terminus of both proteins to generate CLC2-truncations and CLC3-truncations, respectively. Full-length CLC2, full-length CLC3, CLC2-truncations, and CLC3-truncations were purified and tested for C. acnes lytic activity in a turbidity reduction assay. The truncated proteins showed both higher soluble protein yields and significantly higher C. acnes lytic activity in the turbidity reduction assay (Figures 5A-5B). C-terminal truncations were also generated for CLC16 and CaLys1 and tested in a turbidity reduction assay against their full-length counterparts. In all cases, the truncations showed improved solubility and lytic activity compared to their full-length counterparts (Figures 5C-5D). These data demonstrate that removal of the C-terminal region of CLC1 family proteins and CaLys1 results in a positive effect on solubility and activity in turbidity reduction assays. The improved solubility and activity of CaLys1-truncations are particularly surprising considering the known problems with the solubility and activity of full-length CaLys1. Table 5 provides the sequences of truncations of the CLC1 family and CaLys1 truncations, all of which are expected to show improved solubility and lytic activity compared to their full-length counterparts, as observed with CLC1, CLC2, CLC3, CLC16, and CaLys1.
[0226] II. Examples 5-7: Novel C. acnes cell wall binding domains Example 5: Identification of CLB1-CLB4 as putative cell wall hydrolases derived from the genera Cutibacterium sp. and Propionimicrobium sp., containing the CW_7 cell wall binding domain.
[0227]
[0204] Many endolysins (particularly those targeting Gram-positive bacteria) contain both an enzyme-active domain (EAD) and a cell wall-binding domain (CBD). This cell wall-binding domain is involved in the recognition and binding of epitopes in the peptidoglycan of target bacteria, thereby transporting the EAD to its target substrate. In this way, the CBD can increase specificity and / or activity. No known CBDs have been shown to recognize and bind to C. acnes. To find CBDs that can recognize C. acnes, the genomes of Cutibacterium sp. species and a broader range of bacteria from the Propionibacteriaceae family were subjected to bioinformatics analysis for putative cell wall hydrolases containing potential cell wall-binding domains. Four putative proteins (CLB1-CLB4) with unknown characteristics were identified from C. avidum (CLB1), C. acnes (CLB2), and Propionimicrobium lymphophilum (CLB3 and CLB4). All four proteins contain an N-terminal amidase domain. CLB1, CLB3, and CLB4 have a putative C-terminal cell wall-binding domain containing two CW_7 domain repeats, while CLB2 has a putative C-terminal cell wall-binding domain containing a single CW_7 repeat (Figure 6).
[0228] Example 6: Identification of a large family of CBD with broad taxonomic diversity, including the CW_7 repeat.
[0205] CLB1-4 CBDs contain one or two CW_7 repeats. The CW_7 repeats are relatively small (37-40aa) and are thought to bind to the peptidoglycan chain. See Bustamante et al., Sci Rep 2017 Nov 28; 7(1):16494. To characterize the taxonomic diversity of the CW_7 repeat, the Uniprot database was searched for proteins containing the CW_7 domain using the Interpro domain entry IPR013168. UniProt contains approximately 1,333 proteins annotated with one or more CW_7 repeats found in a wide range of bacterial species, mainly bacteria of the phyla Actinobacteria and Firmicutes, as well as in related bacteriophage viruses, where they are expressed more small in the phylum Bacteriodota (Figure 7A-7B). The BLASTP search was also performed in a non-redundant protein database using the CLB2-CBD CW_7 repeat sequence as the query. Using this search, 2656 protein sequences were identified with an E value < 0.05. The CW_7 repeat sequences in these proteins ranged from 43.59% to 100% amino acid identity with respect to the CLB2-CBD CW_7 query, and again, these originated from a diverse range of bacterial species and associated viruses. For each protein, the GenBank accession number, sequence number, and the identity percentage of the top CW_7 matches are listed in Table 7. The sequences of CW_7 CBD containing the proteins identified in this search are provided under sequence numbers 282–2938.
[0229] Example 7: CLB1-CBD and CLB2-CBD can target chimeric cell wall hydrolases in C. acnes.
[0206] To demonstrate that newly identified CBD binds to C. acnes, the inventors investigated the possibility of using CLB1 and CLB2 CBD to create chimeric proteins that have activity against C. acnes. To test this idea, the inventors selected the following two endolysins that in nature target other genera of bacteria and do not target C. acnes: CD27L (typically targeting Clostridium difficle) (Mayer et al., J Bacteriol. 2008 Oct; 190(20):6734-40); and PlyGVE2 (derived from a thermophilic phage known to infect Geobacillus sp.) (Jin et al., Microbiology (Reading). 2013 Aug; 159(Pt 8):1597-1605). These two endolysin-derived EADs were fused to either CLB1-CBD or CLB2-CBD. The resulting chimeric proteins were expressed, purified, and tested for their activity against C. acnes in a turbidity reduction assay. Natural CD27L and PlyGVE2 proteins were also expressed, purified, and tested. While natural CD27L and PlyGVE2 showed no lytic activity against C. acnes, the four chimeric CWHs were able to lyse C. acnes, a bacterium well outside the natural target genera of the two originating endolysins. It has been demonstrated that by fusing EADs to CLB1-CBD and CLB2-CBD, chimeric cell wall hydrolases targeting C. acnes can be created (Figures 8A-8B).
[0230] III. Examples 8-19: Novel CLC1 family EAD and CW_7 CBD chimeras Example 8: Chimeras containing CLC1-3 EAD combined with CLB1-4 CBD exhibit anti-C. acnes activity.
[0207] The CLC1 family of amidases consists of an N-terminal amidase with a conserved sequence at its C-terminus. However, although conserved, there is no predictive protein domain encoded by this sequence, and therefore it is not a clear CBD (Figure 4). Therefore, although we do not wish to be bound by any particular theory, we hypothesized that the activity of the CLC1 family amidases could be modified by fusing the CLC1 family's EAD to a CBD that can recognize and bind to C. acnes.
[0231]
[0208] A set of eight chimeric proteins was created, consisting of combinations of EAD derived from CLC1, CLC2, and CLC3 and CBD derived from CLB1, CLB2, CLB3, and CLB4, to test whether CBD from CLB1-CLB4 could target C. acnes. The designs of these proteins are shown in Table 11 below.
[0232] [Table 48]
[0233]
[0209] These eight chimeric proteins were expressed, purified, and tested using a turbidity reduction assay. As shown in Figures 9A and 9B, the natural CLC1 protein was compared with chimeric proteins in which the CLC1 EAD was linked to various candidate CBDs (CLC1-EAD+CLB1-CBD, CLC1-EAD+CLB2-CBD, CLC1-EAD+CLB3-CBD, and CLC1-EAD+CLB4-CBD). The results showed that all four chimeric proteins exhibited higher C. acnes lytic activity in the turbidity reduction assay compared to the natural full-length CLC1 protein. These data suggest that chimeric cell wall hydrolases containing the CLC1 EAD in combination with CBDs from CLB1 to CBL4 can recognize and bind to C. acnes, and can exhibit higher activity against C. acnes compared to natural CLC1. Further turbidity reduction assays demonstrated that the CLC1-EAD+CLB2-CBD chimera exhibited superior anti-C. acnes lytic activity compared to both full-length CLC1 and more active CLC1-truncations (Figure 9C).
[0234]
[0210] Figures 10A and 11A show the results of lysis assays comparing native CLC2 and CLC3 proteins with CLC2-EAD chimeras (CLC2-EAD+CLB1-CBD and CLC2-EAD+CLB2-CBD) and CLC3-EAD chimeras (CLC3-EAD+CLB1-CBD and CLC3-EAD+CLB2-CBD). Both full-length CLC2 and CLC3 exhibited relatively low C. acnes lysis activity. Linking either CLB1 CBD or CLB2 CBD to CLC2 or CLC3 EAD dramatically increased lysis activity compared to native CLC2 or CLC3, similar to the results observed for CLC1. Further turbidity reduction assays demonstrated that the CLC2-EAD+CLB2-CBD chimera performed better than both full-length CLC2 and more active CLC2-truncations (Figure 10B). Similarly, the CLC3-EAD+CLB2-CBD chimera showed improved lysis activity compared to both full-length CLC3 and more active CLC3-truncations (Figure 11B).
[0235] Example 9: Chimeric proteins containing EAD and CW_7 CBD from the CLC1 family exhibit solubility over a wide range of pH values.
[0211] The enzymatic characteristics of two types of CLC1 EAD chimeric proteins (CLC1-EAD+CLB1-CBD and CLC1-EAD+CLB2-CBD) and two types of CLC3 EAD chimeric proteins (CLC3-EAD+CLB1-CBD and CLC3-EAD+CLB2-CBD) were further clarified at various pH levels.
[0236]
[0212] Enzyme activity may be affected by pH. For commercial applications, it is important that the enzyme functions at the pH relevant to that application. For example, in the case of topical skin application, the normal pH of healthy skin is slightly acidic (approximately pH 5-6). In addition, many topical skin products are formulated to be slightly acidic. Therefore, enzymes used in these types of applications should ideally function at pH 5-6. However, it has been reported that well-preserved C. acnes endolysin CaLys1 exhibits maximum activity at pH 7 (see International Publication No. 2021 / 175606). The following four chimeras of this application were tested by turbidity reduction assay in the pH range of pH 4.2 to pH 8.0: CLC1-EAD+CLB1-CBD, CLC1-EAD+CLB2-CBD, CLC2-EAD+CLB1-CBD, and CLC2-EAD+CLB2-CBD. Surprisingly, all four enzymes exhibited maximum solubility at approximately pH 6.0 (Figure 12). Activity increased approximately threefold at pH 6 compared to approximately pH 7.3. Furthermore, these enzymes remained active over a very wide pH range, including the highest (8.0) and lowest (4.2) pH levels tested in this study.
[0237] Example 10: Chimeric proteins containing EAD and CW_7 CBD from the CLC1 family exhibit strong selectivity for C. acnes.
[0213] The following four chimeric enzymes were tested for genus selectivity: CLC1-EAD+CLB1-CBD, CLC1-EAD+CLB2-CBD, CLC3-EAD+CLB1-CBD, and CLC3-EAD+CLB2-CBD. Specifically, these four chimeras were tested for activity against symbiotic skin bacteria of other genera, such as Corynebacterium xerosis, Corynebacterium striatum, and Staphylococcus epidermidis, using a turbidity reduction assay. In all four cases, potent lytic activity against C. acnes was observed, but not against the other symbiotic skin bacteria tested. This demonstrates that these chimeric proteins have the ability to lyse target bacteria associated with acne vulgaris without damaging important symbiotic skin bacteria (Figures 13A-13D).
[0238] Example 11: Chimeric proteins containing EAD and CW_7 CBD from the CLC1 family exhibit remarkable thermal stability.
[0214] Thermal stability is an important factor in commercial applications. The thermal stability of these chimeric enzymes was tested by incubating aliquots of the protein at a range of temperatures for 30 minutes, and then measuring the residual lysis activity in these aliquots in a turbidity reduction assay at room temperature (Figures 14A-14D). The results showed that the CLC1-EAD+CLB1-CBD chimera retained activity up to incubation at 50°C. The CLC1-EAD+CLB2-CBD chimera showed higher thermal stability, retaining some activity up to incubation at 54°C. The two CLC3 EAD chimeric enzymes exhibited even higher thermal stability; the CLC3-EAD+CLB1-CBD chimera retained activity up to incubation at 58°C, and the CLC3-EAD+CLB2-CBD chimera retained some activity even at the highest temperature tested (58°C).
[0239] Example 12: A quantitative elimination assay demonstrated remarkable C. acnes solubility activity by the CLC1-EAD+CLB1-CBD chimera.
[0215] The solubility of C. acnes is measured by a turbidity reduction assay through the observed reduction in optical density. A more direct method for measuring antimicrobial activity is to use a quantitative cell death assay. This assay measures antimicrobial activity by reducing the number of viable cells after incubation with an enzyme. Specifically, approximately 1 × 10⁻⁶ 6 C. acnes cells were incubated with or without the enzyme for 2–6 hours, at which point serial dilutions of the mixture were seeded onto BHI agar plates and the CFU was quantified. This assay tested the CLC1-EAD+CLB1-CBD chimera. The results showed a three-order-of-magnitude decrease in the number of viable C. acnes cells after 6 hours of incubation (Figure 15).
[0240] Example 13: A chimeric CWH containing EAD from the broader CLC1 family in combination with CLB2 CBD exhibits solubility against C. acnes.
[0216] To test the activity levels of a broader CLC1 family of amidase proteins and their ability to function as components of chimeric cell wall hydrolases, chimeric enzymes were constructed by ligating CLC4-CLC17 EADs with CLB2 CBDs. CLC18 EADs and CLC19 EADs have the same amino acid sequence as CLC13 EADs and were therefore not included independently.
[0241]
[0217] Expression vectors containing the cloned CLC1 family's EAD+CLB2 CBD chimeric CWH were used to transform BL21 Escherichia coli (E. coli) cells. Protein expression was induced, and cell lysates were isolated for each chimeric enzyme. These cell lysates were tested for C. acnes lytic activity using a clearing / halo assay. In this assay, six of the tested lysates showed significant clearing, indicating C. acnes lytic activity. These lysates contained chimeric CWHs containing CLB2 CBD combined with EAD derived from CLC4, CLC5, CLC8, CLC10, CLC14, or CLC16. To confirm these results, these chimeric proteins were purified and tested using a turbidity reduction assay (Figures 16A-16F). Proteins were tested at 12 μg / mL. All six chimeric proteins exhibited potent lytic activity against C. acnes, supporting the results of the clearing assay. Further turbidity reduction assays demonstrated that the CLC16-EAD+CLB2-CBD chimera was superior to both full-length CLC16 and the more active CLC16-truncation in terms of anti-C. acnes lytic activity (Figure 16G).
[0242]
[0218] These active CLC1 family EADs exhibit a range of 77% to 96% amino acid identity with respect to one another (Figure 17), demonstrating the broader utility of the CLC1 family proteins as a source of more highly active EADs that can target C. acnes.
[0243] Example 14: Chimeric CWH containing EAD and CLB2 CBD from the CLC1 family exhibits remarkable thermal stability.
[0219] The thermal stability characteristics of chimeric proteins containing EAD from the CLC1 family were elucidated. The thermal stability of these proteins was measured by incubating aliquots of purified chimeric proteins at a specified temperature for 30 minutes. Subsequently, the lysis activity of the incubated enzymes was measured using a turbidity reduction assay against C. acnes and calculated by comparing it with the activity after incubation at room temperature.
[0244]
[0220] The results are shown in Figures 18A-18F. All six proteins retained significant activity after exposure to 45°C. Chimeric CWHs containing EAD derived from CLC4, CLC5, CLC8, CLC10, and CLC14 showed loss of activity after 30 minutes of incubation at 50-55°C, similar to the CLC1-EAD, CLC2-EAD, and CLC3-EAD chimeric proteins. Surprisingly, the CLC16-EAD+CLB2-CBD chimeric protein showed exceptional thermal stability, retaining over 80% of its activity after 30 minutes of incubation at 75°C and over 40% of its activity even after 30 minutes of incubation at 95°C (Figure 18F).
[0245] Example 15: The CLC16 EAD+CLB2 CBD chimera shows stronger selectivity against C. acnes than against symbiotic skin bacteria.
[0221] The CLC16-EAD+CLB2-CBD chimeric CWH was tested for its lytic activity against C. acnes and three symbiotic skin bacteria (C. xerosis, C. striatum, and S. epidermidis) in a turbidity reduction assay. The CLC16-EAD+CLB2-CBD chimeric CWH showed potent selective activity against C. acnes compared to the other three bacteria (Figure 19).
[0246] Example 16: The CLC1-EAD+CLB2-CBD and CLC16-EAD+CLB2-CBD chimeric enzymes are active against a broad panel of Cutibacterium acnes strains and lineages.
[0222] Based on phylogenetic analysis, including the use of polylocus sequencing (MLST) schemes, C. acnes strains can be classified into five major lineages (IA1, IA2, IB, II, and III). See, for example, McDowell et al., Plos One 2012; 7(7): e41480. Lineages IA1 and IA2 are most often associated with acne lesions.
[0247]
[0223] To evaluate the activity of CLC1-EAD+CLB2-CBD and CLC16-EAD+CLB2-CBD chimeric enzymes against various strains of C. acnes, these enzymes were tested in a turbidity reduction assay against a panel of C. acnes strains from various lineages (Table 12).
[0248] [Table 49]
[0249]
[0224] The results are shown in Figures 20A-20D. Both the CLC1-EAD+CLB2-CBD and CLC16-EAD+CLB2-CBD chimeric enzymes showed potent lytic activity against all C. acnes strains tested, indicating that these chimeric enzymes are active against a broad set of C. acnes strains and lineages.
[0250] Example 17: CBD derived from CLB2 increases the enzymatic activity of CaLys1 EAD.
[0225] The well-conserved CaLys1 endolysin commonly found in the C. acnes phage genome is characterized by weak lytic activity, often requiring concentrations above 100 mg / mL to confirm its activity. This activity has also been observed to be largely nonspecific; for example, its activity against S. aureus has been shown to be at a similar level to its activity against C. acnes. See Varotsou C et al., Int J Mol Sci 2023 May 10; 24(10):8523. To test whether CLB2-CBD can improve the activity and specificity of CaLys1-EAD, a CaLys1-EAD+CLB2-CBD chimeric CWH was generated. The CaLys1-EAD+CLB2-CBD chimeric CWH and the native CaLys1 protein were expressed and purified. The lytic activity of this chimera was compared to that of native proteins in turbidity reduction assays against C. acnes, C. striatum, and S. aureus. These assays utilized a concentration of 12 μg / mL for each protein.
[0251]
[0226] The results are shown in Figures 21A-21C. At these low concentrations, CaLys1 did not exhibit detectable lytic activity against any of the three bacteria. In contrast, the CaLys1-EAD+CLB2-CBD chimeric CWH showed potent lytic activity against C. acnes, but no detectable lytic activity against C. striatum and S. aureus. These data demonstrate that CBD derived from CLB1-CLB4 proteins can increase the C. acnes-specific lytic activity of standard CaLys1 EAD in the chimeric CWH. While CaLys1 has been reported to have equivalent lytic activity against C. acnes and other bacteria (e.g., S. aureus), a chimeric CWH containing CLB2-CBD in combination with CaLys1-EAD showed high C. acnes-specific lytic activity without increasing C. striatum or S. aureus lytic activity. Further turbidity reduction assays also demonstrated that the CaLys1-EAD+CLB2-CBD chimera exhibited higher anti-C. acnes-lytic activity compared to both full-length CaLys1 and more active CaLys1-truncations (Figure 22).
[0252] Example 18: Diverse CW_7 repeats can promote the binding and lysis of C. acnes in chimeric CWH during whole cell lysate screening.
[0227] To test the ability of diverse CW_7-containing CBDs to target C. acnes in chimeric CWHs, 67 CBDs were selected from a wide range of bacterial species and viruses identified in Example 6. These CBDs contained 1 to 4 CW_7 repeats with amino acid identity ranging from 58.5% to 89% relative to the CLB2-CBD CW_7 sequence. The EADs associated with these CBDs contained both amidase and glycohydrolase. Chimeric proteins containing CLC2-EAD were generated by combining each of these CW_7-containing CBDs. These proteins were expressed in BL21 Escherichia coli (E. coli) cells. The whole cell culture lysates were tested for C. acnes-lytic activity in a turbidity reduction assay. The activity was measured in comparison to the activity of the CLC2-EAD+CLB2-CBD chimeric CWH. The results are shown in Figures 23A-23B. Of the 67 CBDs tested, 9 were classified as not having detectable activity in this assay (relative activity < 0.4), likely due to solubility or assay format; 9 had "detectable activity" (relative activity between 0.4 and 0.6); and 49 had "potent activity" (relative activity > 0.6).
[0253]
[0228] CBD found to have "potent" or "detectable" activity consisted of CW_7 repeats ranging from 58.5% to 89% AA ID to CLB2-CBD CW_7, and originated from a wide range of bacterial species (Table 13). These diverse CBD-containing chimeras showed similar activity to that observed in the more highly active CLC2-EAD+CLB2-CBD chimeras. Surprisingly, these data suggest that the C. acnes-specific solubility of EAD can be improved by combining EAD with CBD containing a diverse range of CW_7 repeats, regardless of taxonomic origin or amino acid identity to CLB2-CBD.
[0254]
[0229] CBD-derived CW_7 repeat sequences with potent or detectable activity were edited and bioinformatics analyzed using MEME (see Bailey et al., “The MEME Suite,” Nucleic Acids Research, 2015; 43(W1): W39-W49), a bioinformatics tool for discovering novel gapless sequence motifs in nucleotide and protein sequences. MEME identified two similar amino acid motifs characteristic of the analyzed CBDS. The 21 amino acid motifs contained 12 highly conserved residues, while the 19 amino acid motifs contained 10 highly conserved residues, illustrating the CW_7 repeats found in CBD that can be utilized by chimeric cell wall hydrolases to increase activity against C. acnes. Figure 23C visually represents the relative frequencies of amino acids at each position in this conserved stretch of the CW_7 repeat sequence characterized in this embodiment. The identified motif sequences are as follows:
[0255]
[0230] CW_7-21 motif: LAXXVI / LXGXXGN / SGXXRK / RXXLG (Sequence ID 2940); and
[0256]
[0231] CW_7-19 motif: AXXVI / LXGXXGN / SGXXRK / RXXL (Sequence ID 2941).

[0263] [Table 56]
[0264] Example 19: CW_7 CBD from Actinobacteria, viruses, and Firmicute promotes the binding and lysis of C. acnes in chimeric CWH in a turbidity reduction assay.
[0232] From the diverse CW_7-containing CBDs identified in Example 6 and investigated in Example 18, six CBDs were selected for protein purification and activity testing, with emphasis on selection from diverse classifications and similarity ranges to the CLB2-CBD CW_7 sequence. Thus, two candidates were selected from each of the Actinobacteria diversity, viral diversity, and Firmicute (also known as "bacillota") diversity. These six CBDs contained 2 to 4 CW_7 repeats, and the top CW_7 sequence matching ranged from 63% to 89% amino acid identity to the CLB2-CBD CW_7 sequence, as listed in Table 14. Chimeric proteins containing CLC2-EAD were generated by combining each of these CW_7-containing CBDs. These proteins were expressed in BL21 Escherichia coli (E. coli) cells, purified using a C-terminal 6xHis tag, and assayed for C. acnes lytic activity in a turbidity reduction assay. For control, the results were compared to full-length CLC2 protein, CLC2-truncation, and CLC2-EAD+CLB2-CBD chimeric protein. As shown in Figures 24A-24B, all six diverse CW_7 chimeric proteins exhibited potent C. acnes lytic activity compared to full-length CLC2 and the more active CLC2-truncation, indicating that these CW_7 repeat-containing CBDs enhance the C. acnes lytic activity of CLC1 family EADs. These data suggest that CW_7 repeat-containing CBDs from diverse biological sources can promote C. acnes binding and lysis.
[0265] [Table 57]
[0266] Example 20: A single CW_7 repeat sufficient to increase anti-C. acnes activity in a chimeric combination of the CLC1 family with EAD
[0233] CLB1-CBD contains two CW_7 repeats, CLB1-CW7-1 (SEQ ID NO: 45) and CLB1-CW7-2 (SEQ ID NO: 46), which are 82% identical at the amino acid level. To test whether either single CW_7 repeat is sufficient to improve the activity of the native CLC1 protein, two chimeric proteins were constructed by linking CLC1-EAD to individual CW_7 repeats of CLB1: CLC1-EAD+CLB1-CW7-1-CBD (SEQ ID NO: 2942) and CLC1-EAD+CLB1-CW7-2-CBD (SEQ ID NO: 2943). The sequences of these chimeric proteins are shown in Table 15.
[0267] [Table 58]
[0268]
[0234] These chimeric proteins were expressed and purified, and then tested in a turbidity reduction assay against C. acnes. The results are shown in Figure 25, along with the activity of the natural full-length CLC1 enzyme, which is shown for comparison. In both cases, the chimeric proteins containing a single CW_7 repeat from CLB1-CBD showed significantly improved activity compared to the natural CLC1 protein, demonstrating that a single CW_7 repeat from CBD containing multiple CW_7 repeats is sufficient to improve the activity of the CLC1 family of enzymes.
[0269] Example 21: The topical hydrogel formulation of the chimeric protein retained potent solubility against C. acnes.
[0235] CLC1-EAD+CLB2-CBD chimeric enzyme (SEQ ID NO: 53) and CLC16-EAD+CLB2-CBD chimeric enzyme (SEQ ID NO: 106) were formulated at a concentration of 12 μg / mL in a hydroxypropyl methylcellulose (HPMC)-based hydrogel. HPMC is a commonly used component in skincare formulations. These formulations were incubated at room temperature for 7 days, and then aliquots were used in a quantitative killing assay for C. acnes. In short, approximately 1 × 10⁶ C. acnes were killed. 6 Cells were added to either a hydrogel control (without enzyme) or a hydrogel containing the enzyme. After 6 hours of incubation, the amount of surviving C. acnes cells was measured by serial dilution on a BHI plate incubated at 37°C under anaerobic conditions for 4-5 days. The results are shown in Figure 26. The preparations containing either enzyme showed a reduction of 3-4 orders of magnitude in the size of surviving C. acnes cells compared to the preparation control, demonstrating that these chimeric enzymes were stable and retained their enzymatic activity in the topical preparations.
[0270] Materials and methods
[0236] The main materials and methods used in the examples are described below.
[0271] Phylogenetic analysis of CLC1 family proteins and their amidase domains
[0237] Multiple sequence alignments of CLC1-CLC19 compared to well-conserved members of the CaLys1 endolysin family found in C. acnes and C. acnes phage were generated using MUSCLE (world wide web at ebi.ac.uk / Tools / msa / muscle / ) and visualized as a rootless tree using standard parameters with the Interactive Tree of Life online tool (world wide web at academic.oup.com / nar / article / 49 / W1 / W293 / 6246398). Similarly, to specifically analyze the amidase domain, the amino acid sequences encoding the amidase domain in these 100 proteins were plotted using SMART or CDD, and multiple sequence alignments and phylogenetic trees were generated as described above.
[0272] Bacterial strains and culture conditions
[0238] In this study, Cutibacterium acnes (ATCC11827) was grown at 37°C with shaking in Brain Heart Infusion (BHI) Broth containing Oxyrase® for broth to remove dissolved oxygen, or on a BHI plate containing 2% (w / v) agar placed in a GasPak EZ pouch (Becton Dickinson) at 37°C to create an anaerobic environment. Corynebacterium xerosis (ATCC 373) and Corynebacterium striatum (ATCC BAA-1293) were grown in BHI Broth at 37°C. Staphylococcus epidermidis (NRLL B4268) was grown in trypsin soy broth (TSB; Difco, Frankling Lakes, NJ) at 37°C with shaking. Escherichia coli DH10B (Invitrogen, Carlsbad, CA) was used for cloning and preservation. Escherichia coli BL21 (DE3) (EMD Biosciences, San Diego, CA) was used for protein expression. All Escherichia coli (E. coli) strains were grown at 37°C with shaking in 2×YT medium (16 g / L tryptone, 10 g / L yeast extract, 5 g / L NaCl) or on plates containing LB (10 g / L tryptone, 10 g / L NaCl, 5 g / L yeast extract) supplemented with 2% (w / v) agar. 50 μg / ml kanamycin was used for appropriate selection of E. coli clones.
[0273] Construction of full-length cell wall hydrolase, truncated cell wall hydrolase, and chimeric cell wall hydrolase.
[0239] Full-length cell wall hydrolase was synthesized at the NdeI / HindIII site and liated to the NdeI / HindIII site of pET24a(+). The truncated form of cell wall hydrolase was amplified from a full-length wild-type gene containing the NdeI / HindIII site and liated to the NdeI / HindIII site of pET24a(+). In the case of chimeric enzymes, individual enzyme domains containing up to 50 amino acids upstream and downstream were synthesized at the NdeI / SpeI site. Individual cell wall binding domains containing up to 25 amino acids upstream and downstream were synthesized at the SpeI / HindIII site. Chimeric lysin was constructed by liating both the enzyme domain and the cell wall binding domain to the NdeI / HindIII site of pET24a(+).
[0274]
[0240] An expression vector containing a chimeric cell wall hydrolase was chemically transformed into BL21 Escherichia coli (E. coli) for downstream protein expression and purification.
[0275] Protein production and purification
[0241] BL21 cells containing the appropriate expression plasmid were grown in 2×YT medium at 37°C overnight with shaking. The following morning, the cells were returned to a flask containing 50 mL of ZYM-5052 autoinducible medium (Fisher Scientific catalog number NC1093977), diluted to 1:1000, and incubated at 37°C for 2-3 hours with shaking. The flask was then transferred to 22°C and incubated overnight with shaking. The culture was centrifuged to precipitate, the supernatant was drained, and the pellet was stored at -80°C for at least 30 minutes. Each frozen pellet was resuspended in 5 mL of NPI-10 (100 μM Tris pH 8, 300 mM NaCl, 10 mM imidazole) containing 5 mg of lysozyme and 100 units of DNAseI, and incubated at 30°C for 30 minutes with gentle shaking. The cells were then centrifuged until a clear lysate was obtained and a solid pellet was formed. The clear lysate was transferred to a column containing Nickel-NTA Agarose Resin (Gold Bio) suspended in NPI-10. The column was inverted several times to completely resuspend the resin, and incubated at 4°C for at least 1 hour to enable protein binding. Once the resin had completely settled, the lysate was drained from the column, and the column was washed with two column volumes of NPI-20 (100 μM Tris pH 8, 300 mM NaCl, 20 mM imidazole). Then, NPI-250 (100 μM Tris) was added. The protein was eluted by adding 3 mL of pH 8, 300 mM NaCl, and 250 mM imidazole, and the fraction was collected. The protein was quantified, and its purity was confirmed by the Bradford assay, as well as by SDS-PAGE gel and Coomassi staining. The protein was then concentrated and the buffer was changed to protein preservation buffer (50 mM Tris pH 6.8, 300 mM NaCl) using an Amicon Ultra-15 Filter Unit. For long-term storage, the protein was stored at -80°C with 30% glycerol.
[0276] Clearing assay
[0242] Candidate cell wall hydrolases were tested for their lytic activity against C. acnes by a clearing assay. C. acnes was grown on BHI agar plates at 37°C under anaerobic conditions for 4 days. The cells were then harvested from the plates and washed twice with 25 mM HEPES buffer pH 7.3. The washed cells were resuspended in 25 mM HEPES buffer pH 7.3 at 10 OD / mL. Next, 1 mL of cells was mixed with 20 mL of 0.5% agar and poured into a Petri dish. After setting the agar, 15 μL of purified protein from the candidate cell wall hydrolase was spotted onto the agar. The plates were incubated at room temperature, and clearing around the spots was confirmed after 24 hours.
[0277] Turbidity reduction assay
[0243] Purified candidate cell wall hydrolases were tested for their lytic activity against C. acnes by a turbidity reduction assay. C. acnes was grown on BHI agar plates at 37°C under anaerobic conditions for 4 days. The cells were then harvested from the plates and washed twice with 25 mM HEPES pH 7.3. The OD of the cells was measured. 600 The pH was adjusted to approximately 1.0, and in a flat-bottom microtiter plate, the purified protein was mixed with a 2-fold dilution (e.g., 12 μg / mL to 0.75 μg / mL) and 200 μl of 25 mM HEPES pH 7.3 up to a final volume. Then, the OD of each well was measured. 600The specific activity was measured every 2 minutes for 1 hour using a microplate reader, and then every 5 minutes. The specific activity was calculated as previously described (Briers et al., J Biochem Biophys Methods. 2007 Apr 10; 70(3):531-3). To test the thermal stability of the protein, aliquots of the protein were incubated at a temperature in the range of 37°C to 58°C for 30 minutes. The protein was then immediately tested with the turbidity reduction assay described above. To test the pH range of the protein, turbidity reduction assays were performed using 25 mM Tris HCl pH 8.0, 25 mM HEPES pH 7.3, 25 mM citrate buffer pH 6.5, 25 mM citrate buffer pH 6.2, 25 mM citrate buffer pH 5.7, 25 mM citrate buffer pH 5.3, 25 mM citrate buffer pH 4.9, 25 mM citrate buffer pH 4.5, and 25 mM citrate buffer pH 4.2.
[0278] Quantitative death experiment
[0244] The antimicrobial activity of candidate cell wall hydrolases was measured by a quantitative cell death assay. C. acnes was grown on BHI agar plates at 37°C under anaerobic conditions for 4 days. The cells were then harvested from the plates and washed twice with 25 mM HEPES pH 7.3. Approximately 1 × 10 cells per reaction were then measured. 6 The cells were mixed with the desired amount of protein in a final volume of 200 μL of 25 mM HEPES pH 7.3 and incubated at room temperature. At appropriate time points (e.g., 0 and 6 hours), 20 μL of the reaction mixture was taken out, and serial dilutions were plated onto BHI agar plates and grown under anaerobic conditions at 37°C for 4–5 days. The number of viable cells was then calculated by counting the CFU.
