Abstract

Official abstract text for this publication.

The present disclosure relates to a protein having the activity of exporting O-acetylhomoserine and a novel modified protein thereof, a microorganism capable of producing O-acetylhomoserine with enhanced expression of the protein, and a method for producing O-acetylhomoserine using the microorganism.

First claim

Opening claim text (preview).

The invention claimed is: 1. A polypeptide having the activity of exporting O-acetylhomoserine, wherein at least one amino acid selected from the group consisting of phenylalanine at position 30, leucine at position 95, and phenylalanine at position 165 in the amino acid sequence of SEQ ID NO: 1 is substituted with another amino acid. 2. The polypeptide according to claim 1 , wherein phenylalanine at position 30 in the amino acid sequence of SEQ ID NO: 1 is substituted with any one selected from the group consisting of alanine, tryptophan, leucine, valine, glycine, serine, asparagine, aspartic acid, and histidine; leucine at position 95 in the amino acid sequence of SEQ ID NO: 1 is substituted with any one selected from the group consisting of valine, phenylalanine, alanine, glycine, threonine, asparagine, aspartic acid, and histidine; or phenylalanine at position 165 in the amino acid sequence of SEQ ID NO: 1 is substituted with any one selected from the group consisting of alanine, tryptophan, leucine, valine, glycine, serine, asparagine, aspartic acid, and histidine. 3. The polypeptide according to claim 1 , wherein valine at position 1 in the amino acid sequence of SEQ ID NO: 1 is further substituted with methionine. 4. The polypeptide according to claim 1 , wherein the polypeptide is selected from the group consisting of amino acid sequences of SEQ ID NOS: 133, 134, 137, 138, 141, and 142.
