individual overexpression of ASPDH, aspartate-semialdehyde dehydrogenase from Tistrella mobilis, dihydrodipicolinate reductase from Escherichia coli, and diaminopimelate dehydrogenase from Pseudothermotoga thermarum in Corynebacterium glutamicum LC298, a basic lysine producer, increases the production of lysine by 30.7%, 32.4%, 17.4%, and 36.8%, respectively. The highest increase of lysine production (30.7%) is observed for a triple-mutant strain (27.7 g/L, 0.35 g/g glucose) expressing ASPDH, aspartate-semialdehyde dehydrogenase from Tistrella mobilis, dihydrodipicolinate reductase from Escherichia coli. A quadruple-mutant strain expressing all of the four NADH-utilizing enzymes allows high lysine production (24.1 g/l, 0.30 g/g glucose) almost independent of the oxidative pentose phosphate pathway |
