Catechol O-methyltransferase (COMT) catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to catechol substrates such as the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the main degradative pathways of the catecholamine transmitters. COMT is located in the postsynaptic neuron and is involved in the metabolism of catechol estrogen drugs used in the treatment of hypertension, asthma, Parkinson’s disease and the inactivation of catecholamine neurotransmitters through enzymatic degradation. COMT appears in tissues in 2 forms, a soluble form and a membrane-bound form which differ in their N-termini. COMT inhibitors prevent L-DOPA degradation, increase its availability and are used in the treatment of patients with Parkinson’s disease.

COMT Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 221 amino acids (51-271 a.a.) and having a molecular mass of 24.4 kDa. It is purified by proprietary chromatographic techniques. Purity is greater than 95.0% as determined by SDS-PAGE. COMT protein is provided in 20mM Tris-buffer, pH-8, 1mM MgCl2 and 10% Glycerol.
