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.

Method of producing L-lysine

The L-lysine-producing ability and the L-lysine-producing speed are improved in a coryneform bacterium harboring an aspartokinase in which feedback inhibition by L-lysine and L-threonine is substantially desensitized, by successively enhancing DNA coding for a dihydrodipicolinate reductase, DNA coding for a dihydrodipicolinate synthase, DNA coding for a diaminopimelate decarboxylase, and DNA coding for a diaminopimelate dehydrogenase.

A reference voltage generating circuit generates a reference voltage Vref. An A/D converting circuit compares an analog input voltage Vin with the reference voltage Vref to convert the analog input voltage Vin to a digital output value Dout. A measured value storing circuit stores a measured value of the reference voltage Vref in advance and outputs the stored measured value. A user of an A/D converter corrects the digital output value Dout from the A/D converting circuit by use of the measured value of the reference voltage Vref outputted from the measured value storing circuit, thereby obtaining a digital value representing the analog input voltage Vin accurately irrespective of the accuracy of the reference voltage Vref.

An amplifying circuit amplifies and outputs voltage difference between first external input voltage and voltage corresponding to second external input voltage. An A/D converting circuit converts the output voltage of the amplifying circuit into a digital value by comparing it with reference voltage, and outputs it. A bias circuit selects the second external input voltage or voltage obtained by adding bias voltage to the second external input voltage, according to the output voltage of the amplifying circuit, and outputs it as the voltage corresponding to second external input voltage. A first storing circuit prestores a measured value of the bias voltage, and outputs the stored value as a digital value whose bit number is greater than that of the digital value from the A/D converting circuit, when the voltage corresponding to second external input voltage is the voltage obtained by adding the bias voltage to the second external input voltage.
