EC 2.3.1.74     
Accepted name: naringenin-chalcone synthase
Reaction: 3 malonyl-CoA + 4-coumaroyl-CoA = 4 CoA + naringenin chalcone + 3 CO2

Other name(s): chalcone synthase; flavanone synthase; 6′-deoxychalcone synthase; chalcone synthetase; DOCS; CHS
Systematic name: malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing)
Comments: In the presence of NADH and a reductase, 6′-deoxychalcone is produced.
