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. Group: Enzymes. Synonyms: CYP71AJ1. Enzyme Commission Number: EC 1.14.13.102. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
