cytochrome P450, subfamily IIB. 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. Phosphorylation is accompanied by a decrease in enzyme activity. Note: This description may include information from UniProtKB.
Protein type: Xenobiotic Metabolism - metabolism by cytochrome P450; Lipid Metabolism - arachidonic acid; Oxidoreductase; EC 126.96.36.199; Cofactor and Vitamin Metabolism - retinol; Xenobiotic Metabolism - drug metabolism - cytochrome P450
Molecular Function: iron ion binding; oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen; heme binding; arachidonic acid epoxygenase activity; steroid hydroxylase activity; oxygen binding
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
