ABSTRACT:
The invention relates to mutants and alleles of the coryneform bacterium mqo gene which encodes malate quinone oxidoreductases which contain any amino acid apart from L-serine at position 111, or a comparable position, in the amino acid sequence, and to processes for fermentatively preparing amino acids, preferably L-lysine, L-tryptophan and L-proline, using bacteria which comprise these alleles.
