Other name(s): CYP71AJ4 (gene name)
Systematic name: (+)-columbianetin,[reduced NADPHhemoprotein reductase]:oxygen oxidoreductase
Comments: This cytochrome P-450 (heme-thiolate) enzyme from wild parsnip is involved in the formation of angular furanocoumarins. Attacks its substrate by syn-elimination of hydrogen from C-3'.
