Abstract

Official abstract text for this publication.

The present disclosure relates to a polypeptide having an acyltransferase activity or a microorganism including the same; a composition for preparing N-acetyl-L-methionine, the composition including the polypeptide or microorganism; and a method of preparing N-acetyl-L-methionine using the polypeptide or microorganism. Further, the present disclosure relates to a polynucleotide encoding the polypeptide and an expression vector including the polynucleotide. Since the microorganism including a novel acyltransferase according to the present disclosure has enhanced acyltransferase activity, this microorganism can be efficiently used for producing N-acetyl-L-methionine by acetylating L-methionine.

First claim

Opening claim text (preview).

1 - 8 . (canceled) 9 . The method according to claim 10 , further comprising: recovering N-acetyl-L-methionine, which is the acetylated L-methionine. 10 . A method of preparing N-acetyl-L-methionine, comprising: acetylating L-methionine using (i) a polypeptide having an acyltransferase activity and having the amino acid sequence of any one of SEQ ID NOS. 1 to 3 or the amino acid sequence having 90% or more homology to one of such amino acid sequences; (ii) a microorganism producing N-acetyl-L-methionine from L-methionine, the microorganism comprising the polypeptide or a culture of the microorganism; or (iii) a combination of (i) and (ii). 11 . The method according to claim 10 , wherein the microorganism is selected from the group consisting of Escherichia sp., Corynebacterium sp., Saccharomyces sp., and Yarrowia sp. 12 . The method according to claim 9 , wherein the microorganism is selected from the group consisting of Escherichia sp., Corynebacterium sp., Saccharomyces sp., and Yarrowia sp.
