malonyl-CoA + pelargonidin 3-O-(6-caffeoyl-beta-D-glucoside) 5-O-beta-D-glucoside
CoA + 4'''-demalonylsalvianin
Ss5MaT1 catalyzes the regiospecific transfer of the malonyl group from malonyl-CoA to the 6'''-hydroxyl group of the 5-glucosyl moiety of anthocyanins, e.g. bisdemalonylsalvianin, the presence of an aromatic acyl group at the 3-glucosidic moiety of anthocyanin is important for substrate recognition, strong acyl donor preference for malonyl-CoA

malonyl-CoA + pelargonidin 3-O-(6-caffeoyl-beta-D-glucoside) 5-O-beta-D-glucoside
CoA + 4'''-demalonylsalvianin
Ss5MaT1 catalyzes the regiospecific transfer of the malonyl group from malonyl-CoA to the 6'''-hydroxyl group of the 5-glycosyl moiety of anthocyanins, mechanism, both substrates and Ss5MaT1 form a complex before catalysis can occur, His-167, Asp-390 and Asn-315 are very important for catalytic activity, His-167 and Asp-390 appear to be involved in the general acid/base mechanism
