Metabolite Identification
Common Name2-Hydroxyestradiol
Description2-Hydroxyestradiol is generated from estradiol by a Cytochrome P450. 2-Hydroxyestradiol binds, with a low affinity, to estrogen receptors. It inhbits catechol-O-methyltransferase (COMT) activity. Inactivity of COMT blocks inactivation of catechol hormones and catecholamine neutransmitters. 2-Hydroxyestradiol is also reported to inhibit angiongensis and tumor cell growth (PMID: 9472688 ).

3. Cytochrome P450 1B1
General function:
Involved in monooxygenase activity
Specific 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. Participates in the metabolism of an as-yet-unknown biologically active molecule that is a participant in eye development.
