Abstract
The invention relates to mutants and alleles of the zwf gene of coryneform bacteria, which encode variants of the Zwf subunit of glucose 6-phosphate dehydrogenase (EC: 1.1.1.49), and to processes for preparing amino acids, in particular L-lysine and L-tryptophan, by using bacteria which harbor said alleles.
