Microorganism producing O-acetyl-homoserine and method for producing O-acetylhomoserine using the same

A modified microorganism of the genus Escherichia producing O-acetylhomoserine, wherein an activity of the protein comprising the amino acid sequence of SEQ ID NO:

• 1 in a microorganism of the genus Escherichia capable of producing O-acetylhomoserine is enhanced compared to a non-modified microorganism;
• wherein an activity of cystathionine synthase is weakened or inactivated compared to a non-modified microorganism;
• and
• wherein an activity of homoserine acetyltransferase is further enhanced compared to a non-modified microorganism.
