Identification
HMDB Protein ID CDBP00266
Secondary Accession Numbers Not Available
Name Catechol O-methyltransferase
Description Not Available
Synonyms Not Available
Gene Name COMT
Protein Type Enzyme
Biological Properties
General Function Involved in magnesium ion binding
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.
