text: The inventors of the present invention, as a result of diligent research carried out to overcome the above mentioned problem, have succeeded in obtaining a gene (mutant lysC, or lysC*) which codes for AK III in E. coli and which sufficiently releases the feedback inhibition due to lysine, and have discovered that by introducing this gene into threonine-producing bacteria, L-threonine is efficiently accumulated, and thus the present invention has been completed.
text: The present inventor overcomes the problems referred to above to have carried out diligent research, the result successfully obtains the AK III in a kind of intestinal bacteria of encoding and has fully removed the gene of Methionin feedback inhibition (sudden change lysC or lysC*), and find, in this gene introducing product Threonine bacterium the L-Threonine effectively being accumulated, so just finished the present invention.
