<P>PROBLEM TO BE SOLVED: To provide a gene associated with the polysaccharide production of methanol-assimilating bacteria and the use of the same. <P>SOLUTION: This method for improving or reducing the polysaccharide production activity of the methanol-assimilating bacteria by using DNA's encoding proteins described on any of the following (A) to (D): (A) a protein having a specific amino acid sequence; (B) a protein consisting of amino acid sequences of substituting, deleting, inserting or adding one or in a plurality of amino acids in the amino acid sequence (A) and also having the polysaccharide-producing activity; (C) a protein having the other specific amino acid sequence; and (D) a protein consisting of amino acid sequences of substituting, deleting, inserting or adding one or in a plurality of amino acids in the amino acid sequence (C) and also having the polysaccharide-producing activity. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
