Protein
Chalcone synthase 4-1
Gene
CHS4-1
Organism
Medicago sativa (Alfalfa)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

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 activityi

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