Protein

Chalcone synthase 9

Gene

CHS9

Organism
Daucus carota (Wild carrot)
Status
Reviewed-Annotation score: -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
