Abstract
The ability and speed with which a coryneform bacterium can produce L-lysine are improved when the coryneform bacterium contains an aspartokinase in which feedback inhibition by L-lysine and L-threonine is substantially desensitized. This is accomplished by successively enhancing the DNA coding for dihydrodipicolinate reductase, the DNA coding for dihydrodipicolinate synthase, the DNA coding for diaminopimelate decarboxylase, and the DNA coding for diaminopimelate dehydrogenase.
