General annotation (Comments)

Function	Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.
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.
Induction	By 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).
Sequence similarities	Belongs to the cytochrome P450 family.
