Metabolite Identification

Common Name

2-Hydroxyestradiol

Description

2-Hydroxyestradiol (2-OHE2), also known as estra-1,3,5(10)-triene-2,3,17beta-triol, is an endogenous steroid, catechol estrogen. 2-Hydroxyestradiol belongs to the class of organic compounds known as estrogens and derivatives. These are steroids with a structure containing a 3-hydroxylated estrane. Thus, 2-hydroxyestradiol is considered to be a steroid molecule. It is a metabolite of estradiol, as well as a positional isomer of estriol. Transformation of estradiol to 2-hydroxyestradiol is a major metabolic pathway of estradiol in the liver. 2-Hydroxyestradiol is generated from estradiol via several cytochrome P450 enzymes. Specifically, CYP1A2 and CYP3A4 are the major enzymes catalyzing the 2-hydroxylation of estradiol. Conversion of estradiol into 2-hydroxyestradiol has been detected in the liver, uterus, breast, kidney, brain, and pituitary gland, as well as the placenta. 2-Hydroxyestradiol binds, with a low affinity, to estrogen receptors. 2-Hydroxyestradiol has approximately 7% and 11% of the affinity of estradiol at the estrogen receptors (ERs) ERalpha and ERbeta, respectively (PMID: 9048584 ). 2-Hydroxyestradiol is a catechol estrogen and in this regard bears some structural resemblance to the catecholamines dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline) (PMID: 447670 ). In accordance, 2-hydroxyestradiol has been found to interact with catecholamine systems. The steroid is known to compete with catecholamines for binding to catechol O-methyltransferase and tyrosine hydroxylase and to competitively inhibit these enzymes (PMID: 447670 ). Inactivity of COMT blocks inactivation of catechol hormones and catecholamine neurotransmitters. 2-Hydroxyestradiol is also reported to inhibit angiongensis and tumor cell growth (PMID: 9472688 ).

Specific function:: Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.
Gene Name:: COMT
Uniprot ID:: P21964
Molecular weight:: 30036.77

Reactions

2-Hydroxyestradiol + S-Adenosylmethionine → 2-Methoxyestradiol + S-Adenosylhomocysteine	details

Enzyme Details

2. Protein arginine N-methyltransferase 3

General function:: Involved in protein methyltransferase activity
Specific function:: Methylates (mono and asymmetric dimethylation) the guanidino nitrogens of arginyl residues in some proteins
Gene Name:: PRMT3
Uniprot ID:: O60678
Molecular weight:: 59902.7

Enzyme Details

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.
Gene Name:: CYP1B1
Uniprot ID:: Q16678
Molecular weight:: 60845.33
