Protein

Chalcone synthase A

Gene

CHSA

Organism
Ipomoea purpurea (Common morning glory) (Pharbitis purpurea)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

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.PROSITE-ProRule annotation
