Sysname
malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing)
Reaction(IUBMB)
3 malonyl-CoA + 4-coumaroyl-CoA = 4 CoA + naringenin chalcone + 3 CO2 [RN:R01613]
Reaction(KEGG)
R01613;
(other) R07987 R07988 R07989 R12117
Substrate
malonyl-CoA [CPD:C00083];
4-coumaroyl-CoA [CPD:C00223]
Product
CoA [CPD:C00010];
naringenin chalcone [CPD:C06561];
CO2 [CPD:C00011]
Comment
The enzyme catalyses the first committed step in the biosynthesis of flavonoids. It can also act on dihydro-4-coumaroyl-CoA, forming phloretin.
