METHOD FOR PREPARING GAMMA-AMINOBUTYRIC ACID USING RECOMBINANT ESCHERICHIA COLI STRAINS

摘要

PURPOSE: A method for preparing gamma-amino butyric acid(GABA) from glucose using recombinant E.coli is provided to ensure conversion productivity from glucose to GABA. CONSTITUTION: A method for producing recombinant E.coli for producing GABA(gamma-amino butyric acid) comprises: a step of preparing E.coli in which a gene encoding GabD(succinate-semialdehyde dehydrogenase) and YneI(succinate-semialdehyde dehydrogenase); and a step of transforming the E.coli with a recombinant vector containing a gene encoding succinic semialdehyde dehydrogenase(SucD) and 4-aminobutyrate aminotransferase(GabT).
