In enzymology, an anthocyanin 5-O-glucoside 6'''-O-malonyltransferase (EC 2.3.1.172) is an enzyme that catalyzes the chemical reaction
- malonyl-CoA + pelargonidin 3-O-(6-caffeoyl-beta-D-glucoside) 5-O-beta-D-glucoside CoA + 4'''-demalonylsalvianin
Thus, the two substrates of this enzyme are malonyl-CoA and pelargonidin 3-O-(6-caffeoyl-beta-D-glucoside) 5-O-beta-D-glucoside, whereas its two products are CoA and 4'''-demalonylsalvianin.
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:pelargonidin-3-O-(6-caffeoyl-beta-D-glucoside)-5-O-beta- D-glucoside 6'''-O-malonyltransferase.
