. "Involved in the biosynthesis of chondroitin and dermatan sulfate." . "The human chondroitin synthetase is a bifunctional glycosyltransferase, which also has the EC 2.4.1.175 activity required for the synthesis of the chondroitin sulfate disaccharide repeats." . "Similar chondroitin synthase 'copolymerases' can be found in Pasteurella multocida and Escherichia coli." . "There is also another human protein with apparently only the 3-beta-glucuronosyltransferase activity." . . . "N-acetylgalactosaminyl-proteoglycan 3-beta-glucuronosyltransferase" .
