Accepted name: phenylpropanoylacetyl-CoA synthase

Reaction: (1) feruloyl-CoA + malonyl-CoA = feruloylacetyl-CoA + CO2 + CoA
(2) 4-coumaroyl-CoA + malonyl-CoA = (4-coumaroyl)acetyl-CoA + CO2 + CoA

Glossary: feruloylacetyl-CoA = feruloyl-diketide-CoA
(4-coumaroyl)acetyl-CoA = 4-coumaroyl-diketide-CoA
phenylpropanoylacetyl-CoA = phenylpropanoyl-diketide-CoA

Other name(s): phenylpropanoyl-diketide-CoA synthase; DCS

Systematic name: phenylpropanoyl-CoA:malonyl-CoA phenylpropanoyl-transferase (decarboxylating)

Comments: The enzyme has been characterized from the plant Curcuma longa (turmeric). It prefers feruloyl-CoA, and has no activity with cinnamoyl-CoA.
