SACCHARIDE COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a sulfated fucogalactan decomposable enzyme and to provide a method for obtaining an enzymatically produced sulfated fucogalactan oligosaccharide. SOLUTION: This sulfated fucogalactan is useful as a reagent for sugar chain engineering or a HGF production inducing substance or its salt. This low-molecular weight substance is obtained by treating the sulfated fucogalactan with a sulfated fucogalactan decomposition enzyme or its salt. This sulfated fucogalactan decomposition enzyme is useful for sugar chain enginnering. This method for producing the low-molecular weight substance comprises treating sulfated fucogalactan or its salt with the enzyme. This method for producing the sulfated fucogalactan decomposition enzyme is provided.
