Metabolite Identification
Common NameMethylimidazole acetaldehyde
DescriptionMethylimidazole acetaldehyde belongs to the class of organic compounds known as n-substituted imidazoles. These are heterocyclic compounds containing an imidazole ring substituted at position 1. Methylimidazole acetaldehyde is a very strong basic compound (based on its pKa). Methylimidazole acetaldehyde exists in all living organisms, ranging from bacteria to humans. Within humans, methylimidazole acetaldehyde participates in a number of enzymatic reactions. In particular, methylimidazole acetaldehyde can be biosynthesized from 1-methylhistamine through its interaction with the enzyme amine oxidase [flavin-containing] a. In addition, methylimidazole acetaldehyde can be converted into methylimidazoleacetic acid through the action of the enzyme aldehyde dehydrogenase, dimeric nadp-preferring. In humans, methylimidazole acetaldehyde is involved in histidine metabolism.

Enzymes

Enzyme Details
1. Amine oxidase [flavin-containing] B
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. MAOB preferentially degrades benzylamine and phenylethylamine.
Gene Name:
MAOB
Uniprot ID:
P27338
Molecular weight:
58762.475
Reactions
1-Methylhistamine + Water + Oxygen → Methylimidazole acetaldehyde + Ammonia + Hydrogen peroxidedetails

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

Enzyme Details
3. Aldehyde dehydrogenase, dimeric NADP-preferring
General function:
Involved in oxidoreductase activity
Specific function:
ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. This protein preferentially oxidizes aromatic aldehyde substrates. It may play a role in the oxidation of toxic aldehydes.
Gene Name:
ALDH3A1

Molecular weight:
50394.57
Reactions
Methylimidazole acetaldehyde + NAD + Water → Methylimidazoleacetic acid + NADH + Hydrogen Iondetails
Enzyme Details
4. Aldehyde dehydrogenase family 1 member A3
General function:
Involved in oxidoreductase activity
Specific function:
Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Seems to be the key enzyme in the formation of an RA gradient along the dorso-ventral axis during the early eye development and also in the development of the olfactory system (By similarity).
Gene Name:
ALDH1A3

6. Aldehyde dehydrogenase family 3 member B1
General function:
Involved in oxidoreductase activity
Specific function:
Oxidizes medium and long chain saturated and unsaturated aldehydes. Metabolizes also benzaldehyde. Low activity towards acetaldehyde and 3,4-dihydroxyphenylacetaldehyde. May not metabolize short chain aldehydes. May use both NADP(+) and NAD(+) as cofactors. May have a protective role against the cytotoxicity induced by lipid peroxidation.
