ENZYME entry: EC

Accepted Name
unspecific monooxygenase.
Alternative Name(s)
aryl hydrocarbon hydroxylase.
cytochrome P450.
flavoprotein-linked monooxygenase.
microsomal monooxygenase.
microsomal P450.
xenobiotic monooxygenase.
Reaction catalysed
an organic molecule + O2 + reduced [NADPH--hemoprotein reductase] <=> an alcohol + H(+) + H2O + oxidized [NADPH--hemoprotein reductase]
  • Acts on a wide range of substrates including many xenobiotics, steroids, fatty acids, vitamins and prostaglandins; reactions catalyzed include hydroxylation, epoxidation, N-oxidation, sulfooxidation, N-, S- and O-dealkylations, desulfation, deamination, and reduction of azo, nitro and N-oxide groups.
  • Together with EC, it forms a system in which two reducing equivalents are supplied by NADPH.
  • Some of the reactions attributed to EC belong here.
  • Formerly EC, EC, EC and EC
