Abstract
Anbacterium (1) which harbors dihydrodipicolinate synthase of which feedback inhibition by L-lysine is desensitized and aspartokinase of which feedback inhibition by L-lysine is desensitized, (2) in which intracellular activity of dihydrodipicolinate reductase is enhanced, and (3) in which a diaminopimelate dehydrogenase gene is introduced or intracellular activities of tetrahydrodipicolinate succinylase and succinyl diaminopimelate deacylase are enhanced, wherein intracellular activity of aspartate-semialdehyde dehydrogenase or phosphoenolpyruvate carboxylase is enhanced, is cultured in a suitable medium to produce and accumulate L-lysine in culture, and the L-lysine is collected from the culture.
