摘要:
Disclosed herein are a microorganism strain capable of producing the L-methionine precursor O-acetyl homoserine in high yield and a method of producing O-acetyl homoserine using the same. The microorganism strain is a strain of Escherichia sp. in which an acetyl-CoA synthase gene ( acs ) and/or a pantothenate kinase gene ( coaA ) encoding a pantothenate kinase gene refractory to feedback inhibition by CoA is introduced and expressed.

摘要:
Disclosed is a strain of Escherichia sp., capable of producing O-acetyl homoserine in high yield, with the introduction and enhancement therein of the activity of: homoserine acetyl transferase, aspartokinase and homoserine dehydrogenase; and at least one enzyme selected from a group consisting of phosphoenolpyruvate carboxylase, aspartate aminotransferase and aspartate semi-aldehyde dehydrogenase. Also, a method of producing O-acetyl homoserine using the strain is provided.

Disclosed herein are a microorganism strain capable of producing the L-methionine precursor 0-acetyl homoserine in high yield and a method of producing 0-acetyl homoserine using the same. The microorganism strain is a strain of Escherichia sp. in which an acetyl-CoA synthase gene ( acs ) and/or a pantothenate kinase gene ( coaA ) encoding a pantothenate kinase gene refractory to feedback inhibition by CoA is introduced and expressed.
