Sulfated carbohydrates play an important role in biological phenomena. The conventional chemical methods for sulfation of oligosaccharides involve tedious procedures. In this study, we developed a novel method for the synthesis of sulfated carbohydrates based on enzymatic polymer reaction. To obtain enzymes that show sulfate-transferring activity onto a polysaccharide, arylsulfatases with hydrolytic activity towards arylsulfate derivative was screened. A crude enzyme powders from Aspergillus oryzae showed arylsulafatase activity. Sulfatase-catalyzed sulfation was demonstrated by using p-nitrophenyl sulfate as a sulfate donor and chitooligosaccharides as acceptor, giving rise to a mixture of partially sulfated chitooligosaccharides.
