    摘要: A method of sulfating a polysaccharide is provided. The method can include providing a reaction mixture comprising at least one O-sulfotransferase (OST) enzyme and 3′-phosphoadenosine 5′-phosphosulfate (PAPS); incubating a polysaccharide substrate with the reaction mixture, wherein production of the sulfated polysaccharide from the polysaccharide substrate is catalyzed by the OST enzyme with a conversion of the PAPS to adenosine 3′,5′-diphosphate (PAP); and providing a reaction condition which modifies PAP to reduce an inhibitory effect of PAP on the polysaccharide sulfation.
