Involved in the biosynthesis of coumarins and furanocoumarins (FCs), natural products required for defense responses against attacks by predators with potential medical and agroindustrial usages such as anticoagulant, rodenticide and artificial vanilla substitutes (PubMed:29971079). Able to catalyze the hydroxylation of esculetin to produce 6,7,8-trihydroxycoumarin (PubMed:29971079). Secondary metabolite biosynthesis. Belongs to the cytochrome P450 family.
