Background Technology

[0002] Natural rubber, primarily composed of cis-polyisoprene found in the sap of rubber trees, is widely used in various sectors including the automotive and construction industries, and global demand is expanding. However, because natural rubber is harvested from rubber trees, it is susceptible to supply instability and quality variations, potentially posing significant business risks. Therefore, efforts are underway to develop technologies for the artificial production of natural rubber.

[0100] The base sequences represented by sequence numbers 5, 7, and 9 are the full-length base sequences of CPT6, CPT7, and CPTL from the Brazilian rubber tree (Hevea brasiliensis).

[0101] (Other proteins)

[0102] The protein composition may contain proteins other than those of (A-1), (A-2), and (B). Examples of other proteins include proteins responsible for the polymerization of isoprene in vivo and proteins known to assist polymerization reactions. Examples of the former include the CPT family other than CPT6, CPT7, and CPTL.

[0119] (identity%)

[0120] The identity of the amino acid and base sequences can be 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% or higher. Identity can be determined using, for example, NCBI's BLAST (see http: / / www.ncbi.nlm.nih.gov) under default conditions.

[0121] (The activity possessed by the mutated protein)

[0122] "Having the same activity as each protein" means that, when measured under the same conditions, it has more than 50%, 60%, 70%, 80%, 90%, 95%, or 100% of the activity of each protein.

[0123] (Mutations)

[0124] As long as the aforementioned proteins can maintain the same activity, variations can be introduced at sites within and outside the catalyst domain. The positions of the amino acid residues in the protein capable of maintaining the target activity can be specified by those skilled in the art. For example, those skilled in the art can 1) compare the amino acid sequences of multiple proteins with the same activity (e.g., the amino acid sequence represented by sequence number 6 or 8 and the amino acid sequences of other proteins related to isoprene polymerization), 2) identify relatively conserved or non-conserved regions, and then 3) be able to predict regions that play an important functional role and regions that do not, from the relatively conserved and non-conserved regions, thus identifying structural and / or functional correlations and specifying sites for the introduction of variations.

[0125] The mutation introduced into a protein can be a mutation in which an amino acid residue is replaced by another amino acid residue, preferably a mutation in which an amino acid residue with a similar side chain is replaced. Examples of amino acids classified based on amino acid residues with similar side chains include: amino acids with basic side chains such as lysine, arginine, and histidine; amino acids with acidic side chains such as aspartic acid and glutamic acid; amino acids with non-electrified polar side chains such as asparagine, glutamine, serine, threonine, tyrosine, and cysteine; amino acids with non-polar side chains such as glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan; amino acids with β-branched side chains such as leucine, valine, and isoleucine; amino acids with aromatic side chains such as tyrosine, phenylalanine, tryptophan, and histidine; amino acids with hydroxyl side chains (e.g., alcohols, phenoxy side chains) such as serine, threonine, and tyrosine; and amino acids with sulfur-containing side chains such as cysteine ​​and methionine.

[0126] For the purpose of codon optimization, base sequences can be altered. In this specification, codon optimization refers to altering a base sequence in a way that optimizes expression in a specific target cell without changing the sequence of the encoded polynucleotide. The optimized base sequence can be easily determined by anyone skilled in the art by understanding the frequency of codon usage in the introduced cell and utilizing the degeneracy of the genetic code. Examples of target cells include microorganisms such as Escherichia coli, plant cells, and animal cells.

[0127] (Protein modification)

[0128] Each protein constituting the protein composition may have a purification tag near its C-terminus. Examples of purification tags include, for instance, histidine tags; HA, FLAG, V5, and myc epitopes; chitin-binding protein (CBP); maltose-binding protein (MBP); glutathione-S-transferase (GST); and Strep tags. In addition to the above, the protein composition may also contain factors directly or indirectly related to the polymerization reaction of isoprene.

[0130] The lipid membrane construct of the present invention comprises a lipid membrane containing the above-described protein composition. By using the lipid membrane construct, the protein composition readily exhibits the polymerization activity of isoprene, enabling efficient isoprene polymerization.

[0131] Lipid membranes can be single-layered or bilayered. Examples of single-layered membrane constructs include rubber particles (particles extracted from latex from rubber trees). Examples of bilayered membrane constructs include lipoprotein bodies and artificial lipid membrane models. Artificial lipid membrane models can be composed of natural lipids, synthetic lipids, or both, without particular limitation. Bilayered membrane constructs are preferred, and lipoprotein bodies are more preferred.

[0132] (Lipoprotein bodies)

[0133] In this specification, a liposome is an artificial vesicle in which proteins are encapsulated or bound within a portion of the lipid bilayer membrane of a liposome. In this specification, a liposome is an artificial vesicle that captures aqueous components (usually water) within a space formed by being surrounded by a lipid bilayer membrane. The lipid bilayer membrane is typically composed of lipids such as phospholipids. Examples of phospholipids include phosphatidylethanolamine, phosphatidylcholine, phosphatidylserine, cardiolipin, or combinations thereof. Examples of lipids other than phospholipids include triacylglycerols, waxes, sphingolipids, and sterols and their fatty acid esters, or combinations thereof. The lipids constituting the lipid bilayer membrane preferably include phospholipids derived from organisms, and more preferably include phospholipids derived from soybeans.

[0134] The size of liposomes is not particularly limited, but their diameter is typically 50–300 nm. Liposomes can be naturally derived or synthetic, with the former being preferred, and more preferably derived from plants such as soybeans. Examples of synthetic liposomes include polyalkylene glycol-based liposomes.

[0135] The form in which the protein composition exists in the membrane lipid construct is not particularly limited. In the case of liposomes, it is presumed to be in the form of the protein composition bound to the hydrophilic group portion of the phospholipid on the surface of the liposome (a portion of which may be embedded inside the membrane).

[0136] (Manufacturing method)

[0137] Examples of methods for manufacturing membrane lipid constructs include, for instance, a method that involves expressing polynucleotides encoding proteins constituting the composition in a cell-free protein production system in the presence of a phospholipid-containing raw material.

[0138] The phospholipid-containing raw material includes liposomes when the membrane structure is a lipoprotein. As described above, liposomes of natural origin are preferred, especially those derived from plants such as soybeans.

[0139] The preferred method for manufacturing liposomes includes a step of expressing an expression unit containing the aforementioned polynucleotides in a cell-free protein production system in the presence of liposomes.

[0140] The expression unit contains at least one polynucleotide encoding each protein contained in the protein composition. The polynucleotide is a polynucleotide encoding a protein constituting the protein composition, including (a-1) or (a-2) and (b) above, and further including at least one of (c) to (h) as needed. The expression unit typically contains a promoter. Thus, the expression product of the polynucleotide encoded by the polynucleotide can be produced efficiently. Examples of promoters include the tac promoter, lac promoter, trp promoter, trc promoter, T7 promoter, T5 promoter, T3 promoter, and SP6 promoter, and may contain an enhancer. The promoter is attached to the polynucleotide in a manner that allows the polynucleotide to express itself, for example, attached upstream (5') of the coding sequence. The expression unit can be DNA or RNA, preferably DNA. The expression unit may contain factors such as a terminator, ribosome binding site, drug resistance gene, RNA processing signal, sequence to improve translation efficiency, sequence to improve protein stability, and sequence to improve protein secretion.

[0141] Cell-free protein production systems preferably use cell extracts (e.g., wheat germ extract, Escherichia coli extract, rabbit reticulocyte extract, insect cell extract) via dialysis multilayer method, which can be implemented according to commercially available cell-free protein expression kits.

[0142] Alternatively, other protein construction systems, such as artificial lipid membrane models, can be used instead of liposomes. The protein composition in an artificial lipid membrane model can be constructed using conventional methods. Furthermore, the artificial lipid membrane model can be composed of natural lipids, synthetic lipids, or both; there are no particular limitations.

[0143] (cell)

[0144] The cell of the present invention is a cell that expresses each of the proteins constituting the protein composition (proteins (A), (B), and at least one of (C) to (H) as needed). Examples of cells include, for example, microbial cells such as Escherichia coli and yeast, plant cells, and animal cells, but are not limited thereto.

[0145] The cell preferably contains an expression unit comprising the aforementioned polynucleotide. The expression unit is the same as described in the liposome description. The expression unit that the cell may contain is preferably a heterologous expression unit. In this specification, a heterologous expression unit refers to an expression unit in which at least one of the polynucleotide encoding the protein and the promoter typically included is not inherent to the host cell. Preferably, neither is inherent to the host cell.

[0146] As a method for manufacturing cells, one example is transformation using an expression vector containing an expression unit that encodes polynucleotides encoding each of the proteins constituting the protein composition described above. Since the protein composition, as described above, contains at least two proteins, the expression vector can be one (containing an expression unit with polynucleotides encoding all proteins) or two or more (containing expression units with individual or several polynucleotides). The expression vector can be an integrative vector or a non-integrative vector. In the expression vector, the polynucleotides can be configured under the control of a constitutive or inducible promoter.

[0147] Transformation of a host using an expression vector can be performed using more than one known method. Examples of such methods include the calcium phosphate method, liposome method, DEAE dextran method, electroporation, and particle gun (gene gun). Alternatively, phage vectors other than plasmid vectors can be used to infect bacteria and introduce the vector into the bacterial cell.

[0148] The cell can be a cell containing the aforementioned liposomes. The liposomes are preferably made from naturally occurring liposomes. This allows for easy interaction with the cell membrane. Cells containing liposomes can be manufactured by enabling this interaction. Methods of interaction include, for example, adsorbing or binding the liposomes to the cell surface, allowing the liposomes to enter the cell (endocytosis or phagocytosis), and fusing the lipid bilayer membrane of the liposomes with the cell membrane.

[0149] [Method for manufacturing isoprene polymer compounds]

[0150] The above-mentioned protein composition, lipoprotein bodies, and cells can be used in the manufacture of isoprene polymer compounds.

[0151] In the manufacture of isoprene polymers, an isoprene polymerization reaction is carried out using a low molecular weight allyl compound as a substrate. Examples of low molecular weight allyl compounds include isopentenyl diphosphate and farnesyl diphosphate, with both being preferred. Reaction temperature, reaction time, and other conditions can be appropriately set. Cis-polyisoprene is a representative isoprene polymer, useful as a raw material for rubber. Other examples of isoprene polymers include polyols, polyterpenoids, and their derivatives, which are useful as materials for pharmaceuticals and health foods due to their physiological activities in living organisms (e.g., immune activity, antiviral activity, antioxidant activity). Furthermore, they can also be used as additives (e.g., plasticizers, compatibilizers) in rubber products.

[0152] [Reagent kit for the manufacture of isoprene polymer compounds]

[0153] The aforementioned protein composition, liposomes, and cells can be used as a kit for manufacturing isoprene polymer compounds. The kit typically contains a low molecular weight allyl compound as a substrate. Furthermore, the reaction vessel can contain the desired reagents.

[0154] [Rubber Manufacturing Methods]

[0155] The isoprene polymer compound obtained by the above-described method can be used in the manufacture of rubber.

[0156] The steps and conditions for manufacturing rubber from isoprene polymers can be followed using conventional methods, such as cross-linking and molding the isoprene polymers after mixing. Additives that can be used as needed include, for example, reinforcing agents, silane coupling agents, fillers, vulcanizing agents, vulcanization accelerators, vulcanization aids, oils, curing resins, waxes, anti-aging agents, and colorants. These additives are added at the appropriate stages. The resulting rubber can be used in various applications such as tires, building materials, sporting goods, and automotive parts. Example

[0157] Examples 1-11

[0158] (1) Obtaining the genes for biosynthetic proteins in natural rubber

[0159] Seven proteins (CPT1, CPT2, CPTL, REF1, REF2, REF8, and SRPP1) that are highly produced in latex were selected from the Rubber Database (http: / / Matsui-lab.riken.jp / rubber / home.html). In addition, two proteins (CPT6 and CPT7) were selected from phylogenetic analysis.

[0160] The CPT1, CPT2, CPT6, CPT7, CPTL, REF1, REF2, REF8, and SRPP1 genes were obtained by PCR using cDNA encoding the genes of each protein or plasmids containing the genes as templates. PCR was performed according to the instructions of PrimeSTAR Max DNA Polymerase (Takara) or KOD One PCR Master Mix (TOYOBO), with restriction enzyme digestion sites and His tag sequences added to the primers as needed.

[0161] The primer sets used to obtain the CPT1, CPT2, CPT6, CPT7, CPTL, REF1, REF2, REF8, and SRPP1 genes respectively are primers 1 and 2, primers 3 and 4, primers 5 and 6, primers 7 and 8, primers 9 and 10, primers 11 and 12, primers 13 and 14, primers 15 and 16, and primers 17 and 18.

[0190] (2) Preparation of plasmids for cell-free protein synthesis

[0191] After the PCR reaction products of each gene obtained in (1) above were treated with the restriction enzyme XhoI attached to the primers, the combinations in Table 1 were selected and inserted into the cell-free expression vector pEU-E01-MCS treated with EcoRV and XhoI restriction enzymes, thereby preparing a cell-free protein synthesis plasmid.

[0192] (3) Transformation of Escherichia coli

[0193] The plasmid prepared above was transformed into Escherichia coli JM109, and the transformants were cultured on LB agar medium containing ampicillin. The transformants that had been introduced with the target plasmid were selected by colony PCR.

[0194] (4) Preparation of plasmids for cell-free protein synthesis

[0195] E. coli transformed with a plasmid containing the target gene were cultured overnight on LB liquid medium at 37°C. The bacterial cells were then recovered, and the plasmid was recovered. Plasmid recovery was performed using the FastGene Plasmid Mini Kit (Genetics, Japan). Sequencing analysis confirmed that the nucleotide sequence of the gene inserted into the recovered plasmid was unchanged.

[0196] (5) Transformation of Escherichia coli

[0197] The plasmids prepared above were used to transform Escherichia coli JM109, and the transformants were cultured on LB agar medium containing ampicillin.

[0198] (6) Recovery of plasmids used in cell-free protein synthesis

[0199] After transforming E. coli with a plasmid containing the target gene and culturing it overnight at 37°C on LB liquid medium, the bacterial cells were recovered, and the plasmid was recovered. Plasmid recovery was performed using the QIAGEN Plasmid Midi Kit (QIAGEN), adjusted to 1 μg / μL.

[0200] (7) Synthesis of membrane proteins (liposomes) in the presence of liposomes using multilayer dialysis

[0201] Lipid bilayer membranes (liposomes: approximately several hundred nm in diameter) were prepared using phospholipids derived from soybean. Cell-free protein synthesis was performed under liposome-added conditions according to the protocol provided with the ProteoLiposome BD Expression Kit (CellFreeSciences). For the nine protein expression plasmids serving as templates, the plasmids were adjusted to 1 μg / μL for use in the combinations shown in Table 1, and used in equal proportions to ensure a total volume of approximately 13 μL. For example, in Example 3, 1.5 μL of each of the nine proteins was added to the transcription reaction system, totaling 13.5 μL. After the synthesis reaction, the liposomes containing the nine proteins were simply purified according to the provided protocol, and the synthesis was confirmed by SDS-PAGE.

[0202] (8) Determination of isoprene polymerization activity

[0203] The isoprene polymerization activity of cell-free synthesized proteins was determined by the following method.

[0204] The following solutions were prepared: 50 mM Tris-HCl (pH 7.5), 10 mM MgCl2, 2 mM DTT, 10 μM farnesyl diphosphate (FPP), and 50 μM... 14 C-Isopentenyl diphosphate ( 14 C-IPP (specific radioactivity: 1.48-2.22 GBq / mmol), 100 μL of a reaction solution containing 5 μL of lipoprotein bodies, were reacted at 30°C for 24 hours.

[0205] After the reaction, 200 μL of saturated saline was added, and the reaction product was extracted with 300 μL of water-saturated n-butanol. 400 μL of 2M NaCl was added to the recovered water-saturated n-butanol layer, and after resuspending, the water-saturated n-butanol layer was recovered. 5 mL of Nacalai Tesque was added to 50 μL of the recovered solution, and after thorough mixing, the radiation dose (dpm) was measured using a liquid scintillation counter (LSC-8000; Aloka). The reaction system without liposomes was used as a negative control. The results using liposomes containing various proteins are shown in Table 1.

[0206] (9) TLC images of the products of isoprene polymerization reaction

[0207] The water-saturated n-butanol solution recovered above was used to evaporate the organic layer using a centrifugal evaporator. 1.5 mL of a reaction solution containing a final concentration of 100 mM sodium acetate (pH 5.5), a final concentration of 1 U acid phosphatase, and 1 mL of methanol from potatoes was added, and the mixture was reacted at 37°C for 17 hours.

[0208] After the reaction, the sample was extracted with 500 μL of hexane, and the resulting hexane layer was concentrated and dried using a centrifugal evaporator. The dried product was redissolved with 10 μL of hexane, and the total volume was spotted onto a TLC plate (Merck, TLC glass plate RP-18F254S 5×10 cm). After development with acetone:water = 19:1, the sample was exposed on an imaging plate and visualized using a scanner (Typhoon FLA9500).

[0209] Comparative Example 1 (Negative Control Group)

[0210] Perform the same procedures as in the above examples, except without adding lipoprotein bodies.

[0211] Comparative Examples 2–9 (excluding the negative control group)

[0212] The plasmids for cell-free synthesis of each protein were adjusted to 1 μg / μL. The total amount of plasmids in the reaction was set to 13.5 μL, and each plasmid was added in equal proportions. The same procedures as in the previous examples were then performed.

[0213] [Table 1]

[0214] Table 1. Results of protein combinations and radiation dose measurements for each embodiment.

[0215]

[0216] As clearly shown in Table 1, the radiation doses of each embodiment were higher than those of the comparative examples, and products (presumably with a molecular weight of around 1000-2000) were synthesized. The radiation doses of Example 1 (a combination of CPT6 and CPTL) and Example 2 (a combination of CPT7 and CPTL) were higher than those of the comparative examples, thus confirming that each combination exhibited isoprene polymerization activity. Furthermore, the radiation doses of Examples 3-11, which further incorporated other proteins, were also higher than those of the comparative examples, and also higher than those of Examples 1 and 2, thus confirming the possibility that proteins other than CPT6, 7, and CPTL may also promote isoprene polymerization activity.

[0217] The above results demonstrate that natural rubber can be produced efficiently using this invention.
