VARIANT OF THE cAMP RECEPTOR PROTEIN AND A METHOD FOR PRODUCING AN L-AMINO ACID USING IT

摘要

FIELD: biotech.;SUBSTANCE: invention relates specifically to the recombinant production of amino acids, and can be used to obtain L-amino acids in Escherichia. Proposed is a microorganism of the genus Escherichia containing the cAMP receptor protein, which is a transcriptional regulator, in which the amino acid at position 33 of the amino acid sequence of SEQ ID NO: 1 is replaced by lysine. ;EFFECT: high yield recombinant production of L-amino acids.;9 cl, 11 tbl, 5 ex
