ENZYME entry: EC 1.14.13.102

Accepted Name
Psoralen synthase.
Reaction catalysed
(+)-marmesin + NADPH + O(2) <=> psoralen + NADP(+) + acetone + 2 H(2)O
Comment(s)
  • Specific for (+)-marmesin, and to a much lesser extent 5-hydroxymarmesin, as substrate.
  • Furanocoumarins protect plants from fungal invasion and herbivore attack.
  • (+)-columbianetin, the angular furanocoumarin analog of the linear furanocoumarin (+)-marmesin, is not a substrate for the enzyme but it is a competitive inhibitor.
