Beta-1,3-glucuronyltransferases
beta-1,3-glucuronyltransferases
Beta-1,3-glucuronyltransferases (EC 2.4.1.135) catalyse the following reaction: UDP-glucuronate + 3-beta-D-galactosyl-4-beta-D-galactosyl-O-beta-D-xylosylprotein <=> UDP + 3-beta-D-glucuronosyl-3-beta-D-galactosyl-4-beta-D-galactosyl-O-beta-D-xylosylprotein.
