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.
