Protein

Catechol O-methyltransferase

Gene

Comt

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

S-adenosyl-L-methionine + a catechol = S-adenosyl-L-homocysteine + a guaiacol.

Cofactori

Mg2+By similarityNote: Binds 1 Mg(2+) ion per subunit.By similarity
