ISOLATED POLYNUCLEOTIDE, VECTOR CONTAINING SAME AND HOST CELL AS WELL AS METHOD OF OBTAINING L-AMINO ACIDS

摘要

Isolated polynucleotide (I) is the new zwa1 gene from Corynebacterium glutamicum. Isolated zwa1 polynucleotide (I) contains a sequence that is: (i) at least 70% identical with a sequence that encodes a 199 amino acid (aa) sequence (II), given in the specification; (ii) encodes a polypeptide at least 70% identical with (II); (iii) is the complement of (i) or (ii); or (iv) contains at least 15 consecutive nucleotides (nt) from (i)-(iii). Independent claims are also included for the following: (1) vectors containing (I); (2) coryneform bacterial host cells containing the vector of (1) or having the zwa1 gene amplified; and (3) production of L-amino acids, especially L-lysine, by growing an aa-producing bacterium in which at least the zwa1 gene has been amplified.
