Definitions
- the present invention relates to an Escherichia genus microorganism having L-tryptophan production ability, which is mutated to inactivate the phosphatase, and a method for producing L-tryptophan using the microorganism.
- L-tryptophan is one of the essential amino acids has been widely used as a pharmaceutical raw material and health food material such as feed additives, infusions and the like. As such, L-tryptophan may be produced through chemical synthesis, enzyme reaction, fermentation, etc., but direct fermentation using microorganisms is currently used.
- L-tryptophan-producing strains Development of L-tryptophan-producing strains is initially carried out by mutation screening (Korean Patent Registration No. 1987-0001813), or with the development of genetic engineering to overcome tryptophan feedback inhibition of biosynthetic pathway enzymes, or tryptophan biosynthesis enzymes.
- the development of tryptophan-producing strains was carried out through enhanced enzyme synthesis of metabolic processes, such as enhanced expression.
- tryptophan producing strains with high efficiency yields for industrial use there is still a need for the development of tryptophan producing strains with high efficiency yields for industrial use.
- tryptophan synthase (EC 4.2.1.20), which participates in the final stage of the tryptophan biosynthesis by microorganisms, is known to use PLP (Pyridoxal Phosphate) as a coenzyme.
- PLP Pyridoxal Phosphate
- phosphohydroxythreonine aminotransferase (EC 2.6.1.52) encoded by serC uses PLP as a coenzyme.
- PLP is an important coenzyme.
- the present inventors have made intensive efforts to develop a method for producing L-tryptophan with high efficiency. As a result, the present inventors have tried to prevent degradation of the coenzyme PLP, maintain appropriate concentration of PLP in the cell, and increase tryptophan production ability. As a result of inactivating the protein described by the amino acid of SEQ ID NO: 1 encoded by the yigL gene, which is not yet clear, it was confirmed that tryptophan production ability was improved, thereby completing the present invention.
- One object of the present invention is to provide an Escherichia microorganism having L-tryptophan production capacity.
- Another object of the present invention is to provide a method for producing L-tryptophan using a microorganism having the L-tryptophan production capacity.
- the present invention provides an Escherichia genus microorganism having L-tryptophan production ability, which is mutated to inactivate the activity of phosphatase having the amino acid sequence of SEQ ID NO: 1, thereby using L-tryptophan in a high yield efficiently and economically. It shows the effect that can be produced.
- L-tryptophan prepared through this can be applied to various products such as human food or food additives, pharmaceuticals as well as animal feed or feed additives.
- the genus Escherichia microorganism having L-tryptophan production capacity may be a microorganism having increased tryptophan production capacity compared to the Escherichia genus microorganism having L-tryptophan production capacity that is not changed to inactivate phosphatase activity. have.
- L-tryptophan is one of ⁇ -amino acids and refers to an aromatic L-amino acid having an essential amino acid not synthesized in the body and having a chemical formula of C 11 H 12 N 2 O 2 .
- methods of enhancing the expression of biosynthetic enzymes on the tryptophan production pathway or blocking the side pathways have been used.
- phosphatase may be a protein that catalyzes a reaction for removing phosphate groups from a substrate.
- phosphatase having the amino acid sequence of SEQ ID NO: 1 is a protein encoded by the gene yigL, and is presumed to catalyze the reaction of decomposing pyridoxal and phosphoric acid using PLP as a substrate.
- NCBI For the protein encoded by yigL, NCBI (http://www.ncbi.nlm.nih.gov) DB is named as PLP phosphatase (pyridoxal phosphate phsphatase) (NCBI gene ID: 12930615), EcoCyc DB (http http://www.ecocyc.org) is known as phosphosugar phosphatase, so it is not known which is the main function. Recent studies have reported that yigL expression is induced by heat shock (J. Gen. Appl.
- the enzyme is not only the amino acid sequence set forth in SEQ ID NO: 1, but also 70% or more, specifically 80% or more, more specifically 90% or more, more specifically 95% or more, more specifically Is an amino acid sequence showing at least 98%, more specifically at least 99% homology, and may include any enzyme that has substantially the same or equivalent potency as the enzyme.
- it is an amino acid sequence having such homology and exhibiting efficacy corresponding to each enzyme, it is obvious that enzyme variants having amino acid sequences in which some sequences are deleted, modified, substituted or added are also included within the scope of the present invention.
- the gene encoding the phosphatase described in amino acid sequence number 1 may be included without limitation so long as it is a sequence capable of encoding the enzyme, and may be represented by a yigL gene.
- the gene encoding the enzyme is 80% or more, specifically 90% or more, more specifically 95% or more, more specifically 98% or more with the sequence as well as the nucleotide sequence set forth in SEQ ID NO: 2
- the base sequence may exhibit 99% or more homology, and may include any gene sequence encoding an enzyme having substantially the same or equivalent potency as the enzyme.
- the base sequence having such homology it is obvious that the base sequence in which some sequences are deleted, modified, substituted or added is also included in the scope of the present invention.
- homology refers to the percent identity between two polynucleotide or polypeptide moieties. Homology between sequences from one moiety to another may be determined by known techniques. For example, homology may be sequence information between two polynucleotide molecules or two polypeptide molecules, such as score, identity, and similarity, using a computer program that aligns the sequence information and is readily available. Parameters can be determined by direct alignment (eg BLAST 2.0). In addition, homology between polynucleotides can be determined by hybridization of polynucleotides under conditions of stable double-stranding between homologous regions, followed by digestion with single-strand-specific nucleases to determine the size of the digested fragments.

This is likely due to elevated PLP concentrations in cells.
