Abstract
Provided are a microorganism in which activity of a GNAT family N-acetyltransferase protein is weakened; a method for producing O-acetyl homoserine and L-methionine using the same; a composition for producing O-acetyl homoserine, the composition including the microorganism; and use of the microorganism for producing O-acetyl homoserine or L-methionine.
Claims9
A microorganism of the genus Corynebacterium with an O-acetyl homoserine-producing ability, wherein activity of a GNAT family N-acetyltransferase protein is weakened.
A method for producing O-acetyl homoserine, the method comprising the step of culturing, in a medium, a microorganism of the genus Corynebacterium with an O-acetyl homoserine-producing ability, wherein activity of a GNAT family N-acetyltransferase protein is weakened.
A method for producing L-methionine, the method comprising the steps of:
- culturing, in a medium, a microorganism of the genus Corynebacterium with an O-acetyl homoserine-producing ability, wherein activity of a GNAT family N-acetyltransferase protein is weakened;
- producing O-acetyl homoserine from the cultured microorganism or the medium;
- and
- converting the O-acetyl homoserine into L-methionine.
