Abstract
Description
Technical Field
[0001] The present disclosure relates to a microorganism for producing 1,5-pentanediamine, and in particular to a genetically recombinant microorganism and a method for producing 1,5-pentanediamine using the microorganism. Background Art
[0002] 1,5-Pentanediamine is an important raw material for synthesizing polymers in the chemical industry. The improvement and efficiency enhancement of its production and preparation methods have always been the main topics in this field.
[0003] The in vitro whole-cell biotransformation method is one of the existing methods for producing 1,5-pentanediamine by microorganisms. It uses a complete biological organism as a catalyst for chemical transformation, that is, after the microorganisms are cultured to a certain cell mass, a substrate is added for catalysis and then converted into products. For example, genetically modified microorganisms are used to express lysine decarboxylase (CadA), and the bacterial mass is increased through high-density fermentation to increase the expression of lysine decarboxylase, thereby improving its catalytic conversion efficiency of lysine to produce pentamethylenediamine. However, when producing 1,5-pentanediamine by the whole-cell biotransformation method, expensive pyridoxal 5'-phosphate (PLP) must be added to the reaction system to activate lysine decarboxylase (CadA) to further improve the efficiency of the whole-cell biotransformation method.
[0004] Pyridoxal phosphate (PLP) is the active form of vitamin B6. Escherichia coli cells have two self-generated pathways for pyridoxal phosphate, one of which is the de novo synthesis method, which uses glucose to produce pyridoxal phosphate, and the other is called the super rescue pathway, which uses vitamin B6 precursors such as pyridoxal (PL) and pyridoxine (PN) to catalyze the production of pyridoxal phosphate.
[0005] In the prior art, a method of adding a vitamin B6 precursor to replace pyridoxal phosphate in the catalytic process has been disclosed, such as patent publication number CN109536542A, which discloses adding pyridoxal, pyridoxal phosphate, pyridoxine, pyridoxamine and other coenzymes at a concentration of 0.05 to 0.5 mM in the reaction system; in addition, patent publication number CN109097408A discloses adding lysine decarboxylase and vitamin B6 coenzyme in a continuous enzyme reactor; and patent publication number CN108997141A also discloses adding pyridoxamine, pyridoxine, pyridoxal, pyridoxal phosphate and other vitamin B6 coenzymes in a mixed system of lysine and lysine decarboxylase. However, the above-mentioned direct addition of pyridoxal phosphate precursor is not effective for the production of 1,5-pentanediamine, and other whole-cell catalytic methods for improving the production capacity of 1,5-pentanediamine are still needed.
[0006] In 2015, a research team from Nanjing University of Technology (Ma, W., Cao, W., Zhang, B., Chen, K., Liu, Q., Li, Y., & Ouyang, P. (2015). Engineering a pyridoxal 5'-phosphate supply for cadaverine production by using Escherichia coli whole-cell biocatalysis. Scientific Reports, 5(1), 1-10) attempted to increase the production of pentamethylenediamine by expressing genes in the de novo synthesis pathway, while a team from South Korea led by Kim et al. (Kim, JH, Kim, J., Kim, HJ, Sathiyanarayanan, G., Bhatia, SK, Song, HS & Yang, YH (2017). Biotransformation of pyridoxal 5'-phosphate from pyridoxal by pyridoxal kinase (pdxY) to support cadaverine production in Escherichia coli. Enzyme and Microbial Technology, 104, 9-15) expressed PdxY and added PL as a precursor to obtain a maximum of 33 g / L of pentamethylenediamine with a productivity of 5.5 g / L / h. However, the production capacity and efficiency of these methods do not meet the requirements, so there is still a need for a method to further increase the production of 1,5-pentanediamine.

The present disclosure also provides a recombinant microorganism comprising the expression vector, and a method for producing 1,5-pentanediamine using the microorganism.
[0034] As used herein, the term "pyridoxal phosphate" (PLP) refers to a coenzyme (or auxiliary factor) of lysine decarboxylase that catalyzes the reaction of organisms to produce 1,5-pentanediamine, and pyridoxal phosphate is the active form of vitamin B6. As mentioned above, there are two self-generated pathways for PLP in Escherichia coli cells, one is the de novo synthesis method, that is, the production of PLP using glucose, and the other is the super rescue pathway, that is, the use of vitamin B6 precursors, including pyridoxal (PL) and pyridoxine (PN), etc., to catalyze the production of PLP.
[0035] According to at least one embodiment of the present disclosure, the nucleotide sequence encoding the pdxH gene that produces pyridoxal phosphate is a sequence having at least 80% (e.g., at least 82%, at least 85%, at least 90%, at least 95%, at least 98% or 100%) sequence identity with SEQ ID NO: 1 and having the same activity as SEQ ID NO: 1, for example, a protein having the activity of producing PdxH of pyridoxal phosphate. In some embodiments of the present disclosure, the PdxH that produces pyridoxal phosphate has the amino acid sequence of SEQ ID NO: 2 or an amino acid sequence having conservative variations with SEQ ID NO: 2.
[0036] According to at least one embodiment of the present disclosure, the nucleotide sequence encoding the pdxY gene that produces pyridoxal phosphate is a sequence having at least 80% (e.g., at least 82%, at least 85%, at least 90%, at least 95%, at least 98% or 100%) sequence identity with SEQ ID NO: 3 and having the same activity as SEQ ID NO: 3, for example, a protein having the activity of producing PdxY for producing pyridoxal phosphate. In some embodiments of the present disclosure, the PdxY gene that produces pyridoxal phosphate has the amino acid sequence of SEQ ID NO: 4 or an amino acid sequence that has conservative variations with SEQ ID NO: 4.

[0038] As used herein, the term "sequence identity percentage" refers to the percentage of amino acid or nucleotide residues of a candidate protein or nucleic acid fragment that are exactly the same as the amino acid or nucleotide residues of a reference protein or nucleic acid fragment. When performing the above comparison, the candidate protein or nucleic acid fragment can be first aligned with the protein or nucleic acid fragment, and gaps can be introduced if necessary to allow the two sequences to form the highest sequence identity. When calculating sequence identity, conservatively varied amino acid residues will be considered different residues; nucleotide residues of degenerate codons will also be considered different residues, for example, between the codons AAU and AAC that also encode asparagine, it will be considered that there is a different residue U or C.
[0039] It should be understood that the amino acid or nucleotide sequence of a candidate protein or nucleic acid fragment in which at least a portion of the sequence is modified (e.g., deleted, substituted, or added) compared to the amino acid or nucleotide sequence of the reference protein or nucleic acid fragment in the present disclosure is also within the scope of the present disclosure, as long as the resulting candidate protein or nucleic acid fragment has substantially the same biological activity as the amino acid or nucleotide of the reference protein or nucleic acid fragment, due to the degeneracy of codons. For example, in the nucleotide sequence of the enzyme encoding pyridoxal phosphate producing enzyme disclosed in the present disclosure, various modifications can be made in the coding region, provided that it does not change the activity of the polypeptide expressed from the coding region. Therefore, the nucleotide sequence of the pdxH gene encoding pyridoxal phosphate producing enzyme disclosed in the present disclosure can be a nucleotide sequence having SEQ ID NO: 1 or any nucleotide sequence having at least 80% sequence identity with SEQ ID NO: 1, as long as the protein encoded by the nucleotide sequence can exhibit the activity of PdxH producing pyridoxal phosphate.

[0059]
[0060] The MG1655 genome was used as a template and the above primers were used to perform polymerase chain reaction (PCR) to obtain specific DNA sequence amplification fragments of the relevant genes. The materials required for the PCR reaction for amplifying specific DNA sequence fragments include DNA template, 5' end primer, 3' end primer, triphosphate deoxynucleotide (dNTP), 10x polymerase buffer and polymerase, wherein the polymerase used in this embodiment includes Ex-Taq.

[0061] The amplified gene fragment was digested with HindIII and SpeI, and then the amplified PLP super rescue gene fragment was inserted into the pSU-J23100 or pSU-PlacI vector to construct pSU-J23100-pdxH (indicated by JH, i.e., the pSU-J23100 promoter drives the expression of pdxH gene), pSU-PlacI-pdxH (indicated by PH, i.e., the pSU-PlacI promoter drives the expression of pdxH gene), pSU-J23100-pdxY (indicated by JY, i.e., the pSU-J23100 promoter drives the expression of pdxY gene), pSU-PlacI-pdxY (indicated by PY, i.e., the pSU-PlacI promoter drives the expression of pdxY gene), pSU-J23100-pdxK (indicated by JK, i.e., the pSU-J23100 promoter drives the expression of pdxK gene), And plasmids such as pSU-PlacI-pdxK (indicated by PK, that is, the pSU-PlacI promoter drives the expression of the pdxK gene), and then the plasmids are transformed into the DH5α strain.
[0062] When performing thermal transformation, take a tube of commercially available DH5α competent cells, add about 10μL of the plasmid obtained above, place it on ice for 30 minutes, then heat it in a 42℃ water bath for 1.5 minutes, then place it on ice for 5 to 10 minutes, then add 400μL of LB (Luria Bertani) liquid medium or SOC (super optimal broth with catabolitesrepression) medium, place it in a 37℃ incubator and shake culture for about 60 to 90 minutes, then centrifuge it at 4,000rpm for 3 minutes, remove 300μL of supernatant, and spread all the competent cells containing recombinant DNA on a solid medium containing antibiotics, and culture it at 37℃ overnight. Select a few colonies generated on the solid medium and inoculate them in a liquid medium containing antibiotics, and culture them in a 37℃ incubator overnight to obtain DH5α bacterial liquid containing various plasmids.
[0063] Example 2: Preparation of a continuous self-producing PLP strain and its PLP expression level
[0064] The plasmids pSU-J23100-pdxH, pSU-PlacI-pdxH, pSU-J23100-pdxY, pSU-PlacI-pdxY, pSU-J23100-pdxK and pSU-PlacI-pdxK prepared in Example 1 and stored in DH5α cells were extracted and introduced into Escherichia coli BL21 or W3110 strains through thermal transformation. Competent cells of BL21 or W3110 strains containing the above plasmids were spread on a solid culture medium containing antibiotics and cultured overnight at 37°C. Several cells were then inoculated into a liquid culture medium containing antibiotics and cultured overnight in a 37°C incubator to obtain BL21 or W3110 strains containing the plasmids, which were strains that continuously self-produced PLP.
[0065] The strains that continuously self-produce PLP prepared above were cultured in liquid culture medium, to which 0.2 mM pyridoxine (PN) or pyridoxal (PL) was added for culture, and then the protein expression level of each strain was analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), and the wild-type BL21 or W3110 was used as a control.
[0066] Here we further describe the steps of SDS-PAGE protein analysis. First, cells were collected and adjusted to OD 6004, washed twice with deionized water, and then the cell protein was extracted. Take 30μL of protein sample and mix it with 10μL of protein dye, heat it at 100℃ for 10 minutes, add 15μL of sample solution to the SDS film sample slot, and then perform SDS-PAGE electrophoresis analysis. The setting program of SDS-PAGE is to first perform it at 80V for 30 minutes, then at 120V for 60 minutes, stop when the blue indicator line runs out of the bottom of the film, and then stain with Coomassie Brilliant Blue for 40 minutes to 60 minutes, and decolorize for about 40 minutes. Change the decolorizing solution according to the actual staining situation. After the background blue is completely removed, replace it with deionized water, and scan it after the background color is clear. The results are as follows Figure 1 As shown, the protein expression levels of various plasmids in different host strains and after adding different precursors such as PN or PL were different. For example, when the PL precursor was added, the BL21 strain containing JY, PY and PK plasmids had a higher PLP protein expression.
[0067] The intracellular PLP of the strain was further quantified. The overnight culture cells were quantified to OD 600 The cells were washed three times with sterile water, centrifuged at 12,000 rpm for 3 minutes, and then dissolved in 1 mL of sterile water. The cells were disrupted with a high pressure disruptor at 30 KPsi to obtain intracellular metabolites, 10% trichloroacetic acid was added, and the cells were shaken vigorously and placed on ice for 10 minutes. The proteins were removed by centrifugation at 14,000 g for 10 minutes, and the supernatant was used to quantify the PLP production in the continuous self-producing PLP strain by high performance liquid chromatography (HPLC).
[0068] The HPLC method and analysis conditions for quantitative analysis of PLP include filtering the sample to be analyzed through a 0.2 μm filter membrane, using a reverse phase chromatography C18 column (YMC-C18 column, 4.6×250 mm, particle size 5 μm), eluting with 0.1 M potassium dihydrogen phosphate (pH 6.6) as the elution buffer, eluting for 0 to 20 minutes, and setting the flow rate at 0.8 mL / min. The injection volume is 50 μL. The column temperature is maintained at 35°C, and PLP is measured at a wavelength of 340 nm. Using different concentrations of standard PLP as a control, the PLP concentration in the sample can be measured.
[0069] Figure 2The results of PLP quantification driven by different plasmids in BL21 or W3110 strains are shown, which show that the expression level of pSU-J23100-pdxH (JH) plasmid in the W3110 strain host is significantly different from that of the original strain without any plasmid transformation, while the expression levels of pSU-J23100-pdxH (JH), pSU-PlacI-pdxH (PH), pSU-J23100-pdxY (JY) and pSU-PlacI-pdxK (PK) plasmids in the BL21 strain host are significantly different from that of the original strain without any plasmid transformation.
[0070] Example 3: Preparation of dual-plasmid strains and testing of activity and yield
[0071] The pSIT-CadA expression vector was constructed by amplifying the lysine decarboxylase gene from the genomic DNA of Escherichia coli MG1655 (GenBank: NC_000913), cutting the sticky ends with restriction endonucleases BamHI and NotI, and then ligating into the pSIT vector (pSIT vector purchased from Addgene, vector trade name: pSKDuet16, number: #41684) with ligase to generate pSIT-CadA (SEQ ID NO.20). pSIT-CadA and pSU-J23100-pdxY or pSU-PlacI-pdxK were simultaneously introduced into BL21 cells and selected in a dual resistance medium containing kanamycin and chloramphenicol to construct a dual plasmid strain.
[0072] Next, the biofermentation method was performed, that is, the above dual plasmid system was cultured in a liquid culture medium at 37°C and shaken at 200 rpm. 600 When the pH reached 0.6, 0.01 mM isopropyl β-d-1-thiogalactopyranoside (IPTG), 0.2 mM PN and 50 g / L lysine were added, and the cells were changed to 30°C and cultured with shaking at 200 rpm. Samples were taken at regular intervals to measure cell growth, lysine consumption and pentamethylenediamine production.
[0073] like Figure 3AAs shown in the results, after 10 hours, the biomass of the dual-plasmid system containing pSIT-CadA and pSU-J23100-pdxY (AJY) and the dual-plasmid system containing pSIT-CadA and pSU-PlacI-pdxK (APK) was higher than that of the strain containing only pSIT-CadA (A), indicating that their growth was better. Figure 3B It was shown that AJY could promote the production of pentamethylenediamine in a short time, while APK could achieve the maximum conversion. Figure 3C It was also shown that the dual-plasmid system has a high ability to self-generate PLP.
[0074] The whole-cell transformation was performed using a dual-plasmid system, which included collecting cells cultured overnight by centrifugation at 8,000g for 5 minutes, washing them twice with pure water, and then placing them in lysine solutions of different concentrations. The whole-cell catalytic reaction was performed at 37°C and 200 rpm. After a certain period of time, the reaction solution was boiled at 100°C for 10 minutes, and then the supernatant was obtained by high-speed centrifugation, and the lysine consumption rate and pentamethylenediamine production rate were quantitatively analyzed by HPLC.
[0075] The HPLC quantitative analysis of lysine and pentamethylenediamine derivatization system consisted of 340 μL of 0.05 M boric acid buffer (pH 9), 240 μL of 100% methanol, 6 μL of sample and 12 μL of 200 mM diethylethoxymethylenemalonate (DEEMM). The above sample was heated at 70°C for 2 hours to completely degrade excess DEEMM and derivatization byproducts. After derivatization with DEEMM, HPLC was used for analysis. The C18 column (YMC-C18 column, 4.6×250 mm, particle size 5 μm) was maintained at 35°C. Mobile phase A consisted of 100% acetonitrile, and mobile phase B consisted of 25 mM sodium acetate aqueous solution (pH 4.8). A flow rate of 0.8 mL / min was used with the following gradient program: 0–2 min, 20–25% A; 2–32 min, 25–60% A; 32–40 min, 60–20% A. Detection was performed at 284 nm.
[0076] Figure 4 The catalytic effect of the dual-plasmid system at different concentrations of lysine was shown. The results showed that the APK system had the best catalytic ability and the highest pentamethylenediamine yield and lysine consumption rate.
[0077] Example 4: Comparison of the activity of self-generated PLP domesticated strains
[0078] A continuous self-producing PLP strain was obtained by domestication, including culturing the W3110 strain containing pSU-J23100-CadA in an LB liquid medium containing a high concentration of pyridoxal (PL), wherein the concentration of pyridoxal (PL) was 10 to 150 μM, and inoculating the strain into a fresh medium containing a high concentration of pyridoxal (PL) after overnight culture, and repeating the subculture 10 times. The above strain was evenly spread on an LB agar medium (pH 5.0) containing 20 g / L lysine and 100 μM pyridoxal (PL), and the obtained single colonies were selected for CadA enzyme activity test, and the strain with the highest enzyme activity was screened out, thereby obtaining a self-producing PLP strain that simultaneously expresses CadA and PLP-related genes (hereinafter referred to as JcadA-Wmut to represent this domesticated strain).
[0079] The cells cultured overnight were collected by centrifugation at 8000 x g for 5 minutes, washed twice with pure water, and then put into 1.2 M lysine solution. Different precursors such as PLP, PN or PL were added. The whole-cell catalytic reaction was carried out at 37°C and 200 rpm shaking. The CadA activity was determined by bromophenol purple test (BP test) according to the literature (Ting, WW, Huang, CY, Wu, PY, Huang, SF, Lin, HY, Li, SF, Chang, JS&Ng, IS (2021). Whole-cell biocatalyst for cadaverine production usingstable, constitutive and high expression of L-lysine decarboxylase inrecombinant Escherichia coli W3110. Enzyme and Microbial Technology, 109811).
[0080] The BP analysis steps for determining lysine decarboxylase (CadA) activity are as follows: first, obtain OD 600The bacterial cells obtained after the liquid culture with a quantitative value of 5 were subjected to high pressure sterilization (30Kpsi) and centrifuged at 12,000 rpm for 5 minutes to obtain a soluble protein sample containing lysine decarboxylase. The relationship between different concentrations of lysine and the maximum reaction rate was initially tested, and it was found that the best correlation between pentamethylenediamine and HPLC results was obtained when the initial lysine concentration was 40mM. The BP analysis method will appear purple in alkaline conditions and yellow in acidic conditions. After the reaction of lysine decarboxylase, pentamethylenediamine can be increased and the pH can be increased. Therefore, the BP analysis method can detect the color at a wavelength of 595nm to determine the activity of lysine decarboxylase (CadA).
[0081] The activity of lysine decarboxylase was measured using the reaction conditions in Table 2 below. Finally, 3% trichloroacetic acid (TCA) was added to terminate the reaction of lysine decarboxylase. The change in wavelength at 595 nm (△OD 595 ) A calibration curve was obtained by quantification of pentamethylenediamine via HPLC.

[0084] *PLP can be omitted when testing the CadA enzyme activity of mutant strains
[0085] like Figure 5 As shown, the CadA activity of JcadA-Wmut was highest when PL was added as a cofactor, and was even higher than when PLP was added as a cofactor.
[0086] In addition, if Figure 6 As shown, when PL is used as a precursor and JcadA-Wmut is used as a biocatalyst, 1.2 M lysine can be completely converted into pentamethylenediamine without adding the auxiliary factor PLP, and ultimately a pentamethylenediamine conversion rate of more than 95% and a pentamethylenediamine yield of 124 g / L can be achieved.
[0087] Example 5: Use of JcadA-Wmut as a recycling catalyst
[0088] The cells in the 2M lysine whole cell catalyst solution were centrifuged at 12,000 rpm for 1 minute, recovered, and then placed in a 2M lysine solution. New JcadA-Wmut strain cells were added. The amount of addition was measured by OD 600 The values were 1, 2, 3 and 5 respectively, and the process was repeated twice. The catalytic time was 4 hours each time. The concentrations of lysine and pentamethylenediamine in the catalyzed solution were quantified by HPLC.
[0089] The results are as follows Figure 7 As shown, JcadA-Wmut increased at each feeding OD 600 When the value is 5, it can be recycled at least twice and still maintain a lysine conversion rate of more than 95%.
