[[http://www.uniprot.org/uniprot/CP2A6_HUMAN CP2A6_HUMAN]] Exhibits a high coumarin 7-hydroxylase activity. Can act in the hydroxylation of the anti-cancer drugs cyclophosphamide and ifosphamide. Competent in the metabolic activation of aflatoxin B1. Constitutes the major nicotine C-oxidase. Acts as a 1,4-cineole 2-exo-monooxygenase. Possesses low phenacetin O-deethylation activity.<ref>PMID:1889415</ref> <ref>PMID:1944238</ref> <ref>PMID:11695850</ref> <ref>PMID:16086027</ref> <ref>PMID:17125252</ref> <ref>PMID:18779312</ref>
