Add article description

In enzymology, an anthocyanin 6"-O-malonyltransferase (EC 2.3.1.171) is an enzyme that catalyzes the chemical reaction

malonyl-CoA + an anthocyanidin 3-O-beta-D-glucoside CoA + an anthocyanidin 3-O-(6-O-malonyl-beta-D-glucoside)
Quick Facts "-O-malonyltransferase, Identifiers ...

Thus, the two substrates of this enzyme are malonyl-CoA and anthocyanidin 3-O-beta-D-glucoside, whereas its two products are CoA and anthocyanidin 3-O-(6-O-malonyl-beta-D-glucoside).

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is malonyl-CoA:anthocyanidin-3-O-beta-D-glucoside 6"-O-malonyltransferase.
