EC | 2.3.1.219 | ||
Accepted name: | demethoxycurcumin synthase | ||
Reaction: | (1) 4-coumaroyl-CoA + feruloylacetyl-CoA + H2O = 2 CoA + demethoxycurcumin + CO2 (2) 4-coumaroyl-CoA + (4-coumaroyl)acetyl-CoA + H2O = 2 CoA + bisdemethoxycurcumin + CO2 |

Glossary: | demethoxycurcumin = (1E,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-1,4,6-trien-3-one bisdemethoxycurcumin = (1E,6E)-5-hydroxy-1,7-bis(4-hydroxyphenyl)hepta-1,4,6-trien-3-one feruloylacetyl-CoA = feruloyl-diketide-CoA (4-coumaroyl)acetyl-CoA = 4-coumaroyl-diketide-CoA |

Other name(s): | CURS3 | ||
Systematic name: | 4-coumaroyl-CoA:feruloylacetyl-CoA feruloyltransferase (demethoxycurcumin-forming) | ||
Comments: | 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, curcumin synthase), CURS3 can accept 4-coumaroyl-CoA equally well [1]. | ||
