ID 2.3.1.211 DE bisdemethoxycurcumin synthase. AN curcuminoid synthase. CA 2 4-coumaroyl-CoA + H(+) + H2O + malonyl-CoA = bisdemethoxycurcumin + CA 2 CO2 + 3 CoA. CC -!- A polyketide synthase characterized from the plant Oryza sativa CC (rice) that catalyzes the formation of the C6-C7-C6 diarylheptanoid CC scaffold of bisdemethoxycurcumin. CC -!- Unlike the process in the plant Curcuma longa (turmeric), where the CC conversion is carried out via a diketide intermediate by two CC different enzymes, the diketide intermediate formed by this enzyme CC remains within the enzyme's cavity and is not released to the CC environment. CC -!- Formerly EC 2.3.1.n9. DR Q8LIL0, CUS_ORYSJ ; //
