CATECHOL O-METHYLTRANSFERASECATECHOL O-METHYLTRANSFERASE
Structural highlights
Function[COMT_RAT] 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCatechol O-methyltransferase (COMT, EC 2.1.1.6) is important in the central nervous system because it metabolizes catecholamine neurotransmitters such as dopamine. The enzyme catalyses the transfer of the methyl group from S-adenosyl-L-methionine (AdoMet) to one hydroxyl group of catechols. COMT also inactivates catechol-type compounds such as L-DOPA. With selective inhibitors of COMT in combination with L-DOPA, a new principle has been realized in the therapy of Parkinson's disease. Here we solve the atomic structure of COMT to 2.0 A resolution, which provides new insights into the mechanism of the methyl transfer reaction. The co-enzyme-binding domain is strikingly similar to that of an AdoMet-dependent DNA methylase, indicating that all AdoMet methylases may have a common structure.
