Abstract
The psefdh_D221Q gene encodes a mutant formate dehydrogenase from Pseudomonas (P-seFDG_D221Q), which catalyzes formate oxidation with the simultaneous formation of NADPH. It is expressed in cells of lysine-producing Corynebacterium glutamicum strains. The psefdh_D221Q gene was introduced into C. glutamicum strains as part of an autonomous plasmid or was integrated into the chromosome with the simultaneous inactivation of the host formate-dehydrogenase genes. It was shown that the C. glutamicum strains with NADP+-dependent formate dehydrogenase have an increased level of L-lysine synthesis in the presence of formate if their own formate dehydrogenase is inactivated.
