Enzyme Information

2.3.1.211
Bisdemethoxycurcumin synthase.
based on mapping to UniProt Q8LIL0
2 4-coumaroyl-CoA + malonyl-CoA + H(2)O = 3 CoA + bisdemethoxycurcumin + 2 CO(2).
-!- A polyketide synthase characterized from the plant Oryza sativa (rice) that catalyzes the formation of the C(6)-C(7)-C(6) diarylheptanoid scaffold of bisdemethoxycurcumin. -!- Unlike the process in the plant Curcuma longa (turmeric), where the conversion is carried out via a diketide intermediate by two different enzymes, the diketide intermediate formed by this enzyme remains within the enzyme's cavity and is not released to the environment. -!- Formerly EC 2.3.1.n9.
