substrate specificity, overview. CURS2 prefers feruloyl-CoA as a starter substrate, cf. EC 2.3.1.217, while CURS3 is equally active with both feruloyl-CoA and 4-coumaroyl-CoA. Thus, CURS2 synthesizes curcumin or demethoxycurcumin and CURS3 synthesizes curcumin, bisdemethoxycurcumin and demethoxycurcumin
