CC   -!- FUNCTION: Catalyzes the N-demethylation of aminopyrine and
CC       benzphetamine, but does not catalyze the hydroxylation of tolbutamide,
CC       testosterone, and progesterone.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an organic molecule + reduced [NADPH--hemoprotein reductase] +
CC         O2 = an alcohol + oxidized [NADPH--hemoprotein reductase] + H2O +
CC         H(+); 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   -!- TISSUE SPECIFICITY: Liver.
CC   -!- INDUCTION: P450 can be induced to high levels in liver and other
CC       tissues by various foreign compounds, including drugs, pesticides, and
CC       carcinogens.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
