Sysname
feruloyl-CoA:feruloylacetyl-CoA feruloyltransferase (curcumin-forming)
Reaction(IUBMB)
feruloyl-CoA + feruloylacetyl-CoA + H2O = 2 CoA + curcumin + CO2 [RN:R08810]
Reaction(KEGG)
R08810;
(other) R08808
Show
Substrate
feruloyl-CoA [CPD:C00406];
feruloylacetyl-CoA [CPD:C17741];
H2O [CPD:C00001]
Product
CoA [CPD:C00010];
curcumin [CPD:C10443];
CO2 [CPD:C00011]
Comment
A polyketide synthase from the plant Curcuma longa (turmeric). Three isoforms exist, CURS1, CURS2 and CURS3. While CURS1 and CURS2 prefer feruloyl-CoA as a starter substrate, CURS3 can accept 4-coumaroyl-CoA equally well [2] (see EC 2.3.1.219, demethoxycurcumin synthase).
