ABSTRACT:
A DNA encoding aspartokinase III derived from bacteria of the genus Escherichia and having mutation by which feedback inhibition with L-lysine is released is introduced into cells to form transformant bacteria of the genus Escherichia. These bacteria are incubated in an appropriate culture medium. An L-amino acid is produced and accumulated in the culture, and collected from this culture.
