A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.3.1.219

Accepted Name
Demethoxycurcumin synthase.
Reaction catalysed
  • 4-coumaroyl-CoA + feruloylacetyl-CoA + H(2)O <=> 2 CoA + demethoxycurcumin + CO(2)
  • 4-coumaroyl-CoA + (4-coumaroyl)acetyl-CoA + H(2)O <=> 2 CoA + bisdemethoxycurcumin + CO(2)
Comment(s)
  • 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 (cf. EC 2.3.1.217), CURS3 can accept 4-coumaroyl-CoA equally well.
