    • A recombinant DNA autonomously replicable in cells of coryneform bacteria, comprising a DNA sequence coding for an aspartokinase in which feedback inhibition by L-lysine and L-threonine is substantially desensitized, and a DNA sequence coding for a diaminopimelate decarboxylase; a coryneform bacterium harboring an aspartokinase in which feedback inhibition by L-lysine and L-threonine is substantially desensitized, and comprising an enhanced DNA sequence coding for a diaminopimelate decarboxylase; and a method for producing L-lysine comprising the steps of cultivating the coryneform bacterium in an appropriate medium to allow L-lysine to be produced and accumulated in a culture of the bacterium, and collecting L-lysine from the culture.
    • 在棒状杆菌细胞的细胞中自主复制的重组DNA,其中包含编码天冬氨酸激酶的DNA序列,其中L-赖氨酸和L-苏氨酸的反馈抑制基本上脱敏,以及编码二氨基庚二酸脱羧酶的DNA序列; 携带天冬氨酸激酶的棒状细菌,其中L-赖氨酸和L-苏氨酸的反馈抑制基本上脱敏,并且包含编码二氨基庚二酸脱羧酶的增强的DNA序列; 以及L-赖氨酸的制造方法,其特征在于,在合适的培养基中培养棒状细菌,使L-赖氨酸在细菌培养物中产生并积累,从培养物中收集L-赖氨酸。
