5-Methoxytryptamine

Description

5-Methoxytryptamine, also known as mexamine or 5-MT, belongs to the class of organic compounds known as tryptamines and derivatives. Tryptamines and derivatives are compounds containing the tryptamine backbone, which is structurally characterized by an indole ring substituted at the 3-position by an ethanamine. It is biosynthesized via the deacetylation of melatonin in the pineal gland. 5-MT acts as a full agonist at the 5-HT1, 5-HT2, 5-HT4, 5-HT6, and 5-HT7 receptors. 5-Methoxytryptamine exists in all living organisms, ranging from bacteria to humans. Its affinity for the 5-HT5A receptor is unknown. It has no affinity for the 5-HT3 receptor and is affinity for the 5-HT1E receptor is very weak in comparison to the other 5-HT1 receptors. 5-MT has been shown to occur naturally in the body in low levels.

Enzymes

Enzyme Details

1. Serotonin N-acetyltransferase

General function:: Involved in N-acetyltransferase activity
Specific function:: Controls the night/day rhythm of melatonin production in the pineal gland. Catalyzes the N-acetylation of serotonin into N-acetylserotonin, the penultimate step in the synthesis of melatonin.
Gene Name:: AANAT
Uniprot ID:: Q16613
Molecular weight:: 23343.8

Enzyme Details

2. Amine oxidase [flavin-containing] A

General function:: Involved in oxidoreductase activity
Specific function:: Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOA preferentially oxidizes biogenic amines such as 5-hydroxytryptamine (5-HT), norepinephrine and epinephrine.
Gene Name:: MAOA
Uniprot ID:: P21397
