<P>PROBLEM TO BE SOLVED: To provide a catalyst oxidizing and desulfating a sulfated saccharide having a glucosamine skeleton in a large amount on an industrial scale at a low cost. <P>SOLUTION: The catalyst consists essentially of the following (A) or a protein having functions equal to those of (A) and has an activity of desulfating and oxidizing the sulfated saccharide having the glucosamine skeleton. (A) The protein comprises a specific amino acid sequence. The sulfated saccharide having the glucosamine skeleton is preferably a 6-sulfated saccharide having the glucosamine skeleton, more preferably one or two or more sulfated saccharides selected from 6-sulfated N-acetylglucosamine, N-acetylglucosamine sulfated at both the 2- and the 6-positions and glucosamine sulfated at all of the 2-, the 3- and the 6-positions. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
