NOVEL O-ACETYLHOMOSERINE SULFHYDRYLASE OR VARIANT THEREOF, AND METHOD FOR TRANSFORMING METHIONINE USING SAME

摘要

The present invention relates to a novel protein having O-acetylhomoserine sulfhydrylase activity, a variant protein thereof, a polynucleotide encoding same, a recombinant vector including the polynucleotide, a microorganism transformed by the recombinant vector, and a method for producing methionine or acetic acid using the protein. The method for producing of the present invention has the advantage of economically producing L-methionine and acetic acid by having a higher transformation rate and reduced reaction time compared to existing methods, and can easily produce the L-metionine and the acetic acid with high yield by minimizing the amount of enzyme homogenate injected, when using the variant protein.
