== Function ==
[https://www.uniprot.org/uniprot/COMT_HUMAN COMT_HUMAN] 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.
