General annotation (Comments)

Function

Responsible for mutagenic activation of 3-methoxy-4-aminoazobenzene (3-MeO-AAB); a potent procarcinogen. Also active on 2-aminofluorene and 2-aminoanthracene.

Catalytic activity

RH + reduced flavoprotein + O2 = ROH + oxidized flavoprotein + H2O.

Cofactor

Heme group By similarity.

Subcellular location

Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein.

Tissue specificity

Present abundantly in renal microsomes of male mice but not in those of female mice. Also present in pulmonary microsomes of male and female mice. Not found in liver.

Induction

P450 can be induced to high levels in liver and other tissues by various foreign compounds, including drugs, pesticides, and carcinogens.

Sequence similarities

Belongs to the cytochrome P450 family.
