Cyanidin-3-O-glucoside 2-O-glucuronosyltransferase

Class of enzymes

Cyanidin-3-O-glucoside 2-O-glucuronosyltransferase (EC 2.4.1.254, BpUGT94B1, UDP-glucuronic acid:anthocyanin glucuronosyltransferase, UDP-glucuronic acid:anthocyanidin 3-glucoside 2'-O-beta-glucuronosyltransferase, BpUGAT, UDP-D-glucuronate:cyanidin-3-O-beta-glucoside 2-O-beta-glucuronosyltransferase) is an enzyme with systematic name UDP-D-glucuronate:cyanidin-3-O-beta-D-glucoside 2-O-beta-D-glucuronosyltransferase.[1][2] This enzyme catalyses the following chemical reaction

UDP-D-glucuronate + cyanidin 3-O-beta-D-glucoside UDP + cyanidin 3-O-(2-O-beta-D-glucuronosyl)-beta-D-glucoside
Quick Facts Identifiers, EC no. ...

The enzyme is highly specific for cyanidin 3-O-glucosides and UDP-D-glucuronate.
