Accepted name: angelicin synthase
Reaction: (+)-columbianetin + [reduced NADPH—hemoprotein reductase] + O2 = angelicin + [oxidized NADPH—hemoprotein reductase] + acetone + 2 H2O
Other name(s): CYP71AJ4 (gene name)
Systematic name: (+)-columbianetin,[reduced NADPH—hemoprotein 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′.
