RL Submitted (JAN-2000) to the EMBL/GenBank/DDBJ databases.
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}.
