NEW NUCLEOTIDE SEQUENCE ENCODING GENE sdhA, sdhB AND sdhC

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an amino acid, especially L-lysine by an improved fermentation. SOLUTION: This method for isolating new genes sdhC, sdhA and sdhB from coryneform bacteria is provided, and the improved fermenting method for producing an L-amino acid by attenuating the sdhA-, sdhB- or sdhC-gene- encoding subunits A, B or C of an enzyme, succinic acid dehydrogenase is also provided.
