Anthocyanin 5-O-glucoside 6'''-O-malonyltransferase

In enzymology, an anthocyanin 5-O-glucoside 6  -O-malonyltransferase''' is an enzyme that catalyzes the chemical reaction


 * malonyl-CoA + pelargonidin 3-O-(6-caffeoyl-beta-D-glucoside) 5-O-beta-D-glucoside $$\rightleftharpoons$$ 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'''.
