galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase M-CSA #801 | Beta-1,3-glucuronyltransferase (GlcAT-I) is involved in the biosynthesis of heparin sulphate and chondroitin sulphate. It catalyses the transfer of glucuronic acid (GlcUA) from UDP-GlcUA onto the terminal galactose of the linker Gal-Gal-Xyl- that is attached to a serine side chain of a core protein. GlcAT-I is an inverting glycosyltransferse, converting the alpha linkage in the UDP-GlcUA molecule to a beta linkage in the product. | Defined by 2 residues: ASP:A-122 [auth A-196]GLU:A-207 [auth A-281] | |
