Function
function
The primary product of this enzyme is 4,2',4',6'-tetrahydroxychalcone (also termed naringenin-chalcone or chalcone) which can under specific conditions spontaneously isomerize into naringenin.
Catalytic activity
- (E)-4-coumaroyl-CoA + 3 malonyl-CoA + 3 H+ = 2',4,4',6'-tetrahydroxychalcone + 3 CO2 + 4 CoA
Pathway
Secondary metabolite biosynthesis; flavonoid biosynthesis.
