ABSTRACT
Catechol O-methyltransferase (COMT), one of the endogenous phase II metabolizing enzymes, expressed by chromosome 22. COMT catalyzes the transfer of a methyl group from common methyl donor S-adenosyl-L-methionine (AdoMet or SAM) to one of the catechol hydroxyls. COMT participates in the metabolism of many catechols in vivo, e.g. dopamine, epinephrine, noradrenaline, estradiol. Furthermore COMT also plays important roles in the metabolism of xenobiotic catechols from food and drug. COMT play a critical role in the management of catechols. Metabolism disorders of COMT can cause many diseases or an increased risk of diseases, e.g. Pakinson diseases, schizophrenia, and breast cancer. In this review, we explains the relationship of COMT and related-diseases through expounding disease caused by the COMT metabolic disorders. Finally, we hope that there will be more effective treatments for the COMT metabolism related diseases.
