Blood group B branched chain alpha-1,3-galactosidase (original) (raw)

Heparanase (EC 3.2.1.166, Hpa1 heparanase, Hpa1, heparanase 1, heparanase-1, C1A heparanase, HPSE) is an enzyme with systematic name heparan sulfate N-sulfo-D-glucosamine endoglucanase. This enzyme catalyses the following chemical reaction endohydrolysis of (1->4)-beta-D-glycosidic bonds of heparan sulfate chains in heparan sulfate proteoglycan Heparanase cleaves the linkage between a glucuronic acid unit and an unit carrying either a 3-O-sulfo or a 6-O-sulfo group.
