CC   -!- FUNCTION: Cytochromes P450 are a group of heme-thiolate monooxygenases.
CC       They oxidize a variety of structurally unrelated compounds, including
CC       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         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   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
