psoralen synthase

This microsomal cytochrome P-450-dependent enzyme is 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 analogue of the linear furanocoumarin (+)-marmesin, is not a substrate for the enzyme but it is a competitive inhibitor.
