CC   -!- FUNCTION: The primary product of this enzyme is 4,2',4',6'-
CC       tetrahydroxychalcone (also termed naringenin-chalcone or chalcone)
CC       which can under specific conditions spontaneously isomerize into
CC       naringenin.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-coumaroyl-CoA + 2 H(+) + 3 malonyl-CoA = 2',4,4',6'-
CC         tetrahydroxychalcone + 3 CO2 + 4 CoA; Xref=Rhea:RHEA:11128,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57287,
CC         ChEBI:CHEBI:57355, ChEBI:CHEBI:57384, ChEBI:CHEBI:77645; EC=2.3.1.74;
CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU10023};
CC   -!- PATHWAY: Secondary metabolite biosynthesis; flavonoid biosynthesis.
CC   -!- SIMILARITY: Belongs to the thiolase-like superfamily. Chalcone/stilbene
CC       synthases family. {ECO:0000305}.
