Abstract

The invention relates to mutants and alleles of the gnd gene from coryneform bacteria coding for 6-phosphogluconate dehydrogenases which contain at position 329 or a comparable position of the amino acid sequence any amino acid other than L-valine, and to processes for the production of amino acids, preferably L-lysine and L-tryptophan, by fermentation using bacteria that contain these alleles.
