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. Most active in catalyzing 2-hydroxylation (By similarity).
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.
SIMILARITY: Belongs to the cytochrome P450 family.
