CC -!- FUNCTION: Cytochromes P450 are a group of heme-thiolate monooxygenases.
CC In liver microsomes, this enzyme is involved in an NADPH-dependent
CC electron transport pathway. It oxidizes a variety of structurally
CC unrelated compounds, including steroids, fatty acids, and xenobiotics.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an organic molecule + O2 + reduced [NADPH--hemoprotein
CC reductase] = an alcohol + H(+) + H2O + oxidized [NADPH--hemoprotein
CC reductase]; Xref=Rhea:RHEA:17149, Rhea:RHEA-COMP:11964, Rhea:RHEA-
CC COMP:11965, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC ChEBI:CHEBI:30879, ChEBI:CHEBI:57618, ChEBI:CHEBI:58210,
CC ChEBI:CHEBI:142491; EC=1.14.14.1;
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Peripheral
CC membrane protein. Microsome membrane; Peripheral membrane protein.
CC -!- INDUCTION: By phenobarbital.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
