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.
