catalytic activity:RH + reduced flavoprotein + O(2) = ROH + oxidized flavoprotein + H(2)O.,cofactor:Heme group.,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.,induction:By phenobarbital.,online information:CYP2B6 alleles,PTM:Phosphorylation is accompanied by a decrease in enzyme activity.,similarity:Belongs to the cytochrome P450 family.,tissue specificity:Expressed in liver, lung and heart right ventricle.,
