Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator. Tryptophan hydroxylase Aromatic L-amino acid decarboxylase Aralkylamine N-acetyltransferase Acetylserotonin O-methyltransferase. Tyrosine hydroxylase Aromatic L-amino acid decarboxylase Dopamine beta-hydroxylase Phenylethanolamine N-methyltransferase.

A functional single-nucleotide polymorphism a common normal variant of the gene for catechol-O-methyltransferase results in a valine to methionine mutation at position Val Met rs Please improve this by adding secondary or tertiary sources. Hydroxymethyltransferase Serine hydroxymethyltransferase 3-methyloxobutanoate hydroxymethyltransferase.

American Journal of Human Genetics. Cholinesterase AcetylcholinesteraseButyrylcholinesterase. Both entacapone and tolcapone are well-tolerated. More reference expression data.

Catechol- O -methyltransferase is involved in the inactivation of the catecholamine neurotransmitters dopamineepinephrineand norepinephrine. Lay summary — MedWireNews. They induce a dose-dependent inhibition of COMT activity in erythrocytes and a significant decrease in the plasma levels of 3-O-methyldopa, cot their effectiveness as COMT inhibitors.


For tolcapone and mg have most often proved to be the optimal doses. Goetz CG May Comparable effects on similar cognitive tasks, the frontal lobes, and the neurotransmitter dopamine have also all been linked to schizophrenia. In the brain, COMT-dependent dopamine degradation is of particular importance in brain regions with low expression of the presynaptic dopamine transporter DATsuch as the prefrontal cortex.

Aspartate carbamoyltransferase Ornithine carbamoyltransferase Oxamate carbamoyltransferase Putrescine carbamoyltransferase 3-hydroxymethylcephem carbamoyltransferase Lysine carbamoyltransferase N-acetylornithine carbamoyltransferase. Phosphoribosylglycinamide formyltransferase Inosine monophosphate synthase. Temporomandibular joint dysfunction TMD does not appear to be a classic genetic disorder, however variations in the gene that codes for COMT have been suggested to be responsible for inheritance of a predisposition to develop TMD during life.

Research conducted at the Section of Neurobiology of PsychosisInstitute of Psychiatry, King’s College London has demonstrated an effect of COMT both in patients with bipolar disorder and in their relatives, [36] [ unreliable medical source ] but these findings have not been replicated so far.

EST3 – Inhibidores de la comt. – Google Patents

The O in the name stands for oxygennot for ortho. As the regulation of catecholamines is impaired in a number of medical conditions, several pharmaceutical drugs ckmt COMT to alter its activity and therefore the availability inhinidores catecholamines. Oroszi G, Goldman D December Histamine N-methyltransferase Phenylethanolamine N-methyltransferase Amine N-methyltransferase Phosphatidylethanolamine N-methyltransferase. However, there seems to be a trend for tolcapone to induce more often diarrhoea and increase in liver transaminases compared with entacapone.


COMT inhibition in the treatment of Parkinson’s disease.

From Wikipedia, the free encyclopedia. The British Journal of Psychiatry. This article relies too much on references to primary sources.

Any compound having inhibiodres catechol structure, like catecholestrogens and catechol-containing flavonoids, are substrates of COMT. EC number Enzyme superfamily Enzyme family List of enzymes.

Molecular and Cellular Biology portal. The gene is associated with allelic variants. The enzyme introduces a methyl group to the catecholamine, which is donated by S-adenosyl methionine SAM.

This page was last edited on 21 Novemberat Neurotransmitters and their receptors”. Consequently, they increase the elimination half-life of levodopa and thus prolong the availability of levodopa to the brain without significantly affecting inhubidores Cmax or tmax of levodopa. The best-studied is ValMet. Journal of Alzheimer’s Disease.
