ESCHERICHIA COLI VARIETY PRODUCING L-THREONINE AND METHOD FOR FABRICATING THE SAME

摘要

The present invention relates to a transformed microorganism having improved threonine productivity. More particularly, the present invention relates to a threonine-producing microorganism transformed with a vector comprising a gene encoding an rpoS protein, the amino acid sequence of which has leucine at position 33. The microorganism of the present invention can produce L-threonine in a high yield, thereby being used in medicinal, pharmaceutical, and feed industries, in particular, as an animal feed.
