General annotation (Comments)

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

3 malonyl-CoA + 4-coumaroyl-CoA = 4 CoA + naringenin chalcone + 3 CO2.

Pathway

Secondary metabolite biosynthesis; flavonoid biosynthesis.

Sequence similarities

Belongs to the chalcone/stilbene synthases family.
