Cytochrome P450s from Cynara cardunculus L. CYP71AV9 and CYP71BL5, catalyze distinct hydroxylations in the sesquiterpene lactone biosynthetic pathway
文摘

Two P450 genes (i.e. CYP71AV9 and CYP71BL) involved in sesquiterpene lactone pathway have been isolated in globe artichoke.

CYP71BL5 and CYP71AV9 co-expressed with GAS led to biosynthesis of the free costunolide in yeast and costunolide conjugates in N. benthamiana.

CYP71AV9 converts also non-natural substrates, amorpha-4,11-diene, (+)-germacrene D and cascarilladiene, to oxidized products.
