IntEnz Enzyme Nomenclature
EC 2.3.1.74

Names

Accepted name:
chalcone synthase
Other names:
6'-deoxychalcone synthase
CHS
DOCS
naringenin-chalcone synthase
chalcone synthetase
flavanone synthase
Systematic name:
malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing)

Reaction

Comments:

The enzyme catalyses the first committed step in the biosynthesis of flavonoids. It can also act on dihydro-4-coumaroyl-CoA, forming phloretin.
