CC -!- FUNCTION: Involved in the biosynthesis of coumarins and furanocoumarins
CC (FCs), natural products required for defense responses against attacks
CC by predators with potential medical and agroindustrial usages such as
CC anticoagulant, rodenticide and artificial vanilla substitutes
CC (PubMed:29971079). Involved in angular furanocumarin biosynthesis.
CC Converts (+)-columbianetin to angelicin (PubMed:19098286). Produces
CC also some hydroxycolumbianetin as a by-product (PubMed:19098286). No
CC activity with demethylsuberosin, (+)-marmesin, 5-hydroxymarmesin,
CC psoralen, bergaptol, xanthotoxol, bergapten, xanthotoxin,
CC isopimpinellin, cinnamic acid, 4-coumaric acid, 2-coumaric acid,
CC ferulic acid, coumarin, herniarin, scopoletin, or umbelliferone
CC (PubMed:19098286). The reaction mechanism is initiated by the
CC abstraction of syn-C-3'-hydrogen (PubMed:19098286).
CC {ECO:0000269|PubMed:19098286, ECO:0000303|PubMed:29971079}.
CC -!- CATALYTIC ACTIVITY:

CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000250|UniProtKB:Q94IP1};
CC -!- ACTIVITY REGULATION: Not inhibited by (+)-marmesin, psoralen, 5- or 8-
CC methoxypsoralen and angelicin. {ECO:0000269|PubMed:19098286}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=2.1 uM for (+)-columbianetin {ECO:0000269|PubMed:19098286};
CC KM=1.4 uM for syn-[3'-D]columbianetin {ECO:0000269|PubMed:19098286};
CC pH dependence:
CC Optimum pH is 7.0. {ECO:0000269|PubMed:19098286};
CC Temperature dependence:
CC Optimum temperature is 27-30 degrees Celsius.
CC {ECO:0000269|PubMed:19098286};
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000305|PubMed:29971079}.
CC -!- SUBCELLULAR LOCATION: Microsome membrane
CC {ECO:0000250|UniProtKB:Q6QNI4}; Single-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
