ENZYME entry: EC 1.14.14.141

Accepted Name
psoralen synthase
Reaction catalysed
(7S)-marmesin + O2 + reduced [NADPH--hemoprotein reductase] = acetone + H(+) + 2 H2O + oxidized [NADPH--hemoprotein reductase] + psoralen
Comment(s)
  • This microsomal cytochrome P450 (heme-thiolate) enzyme is rather specific for (+)-marmesin, although it can also accept 5-hydroxymarmesin to a much lesser extent.
  • Furanocoumarins protect plants from fungal invasion and herbivore attack.
  • (+)-columbianetin, the angular furanocoumarin analog of the linear furanocoumarin (+)-marmesin, acts as a competitive inhibitor even though it is not a substrate.
  • Formerly EC 1.14.13.102.
