Metabolite Identification
Common NameMethylarsonite
DescriptionMethylarsonite, also known as meas(OH)2 or mma(iii), belongs to the class of organic compounds known as trivalent organic arsenic compounds. These are organoarsenic compounds in which a carbon is linked to a trivalent arsenic atom. In humans, methylarsonite is involved in the arsenate detoxification pathway. Methylarsonite has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make methylarsonite a potential biomarker for the consumption of these foods. Methylarsonite is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Methylarsonite.

Enzymes

Enzyme Details
1. Arsenite methyltransferase
General function:
Involved in methyltransferase activity
Specific function:
Catalyzes the transfer of a methyl group from AdoMet to trivalent arsenicals producing methylated and dimethylated arsenicals. It methylates arsenite to form methylarsonate, Me-AsO(3)H(2), which is reduced by methylarsonate reductase to methylarsonite, Me-As(OH)2. Methylarsonite is also a substrate and it is converted into the much less toxic compound dimethylarsinate (cacodylate), Me(2)As(O)-OH (By similarity).
Gene Name:
AS3MT
Uniprot ID:
Q9HBK9
Molecular weight:
41747.49
Reactions
S-Adenosylmethionine + Methylarsonite → S-Adenosylhomocysteine + Dimethylarsinic aciddetails
Enzyme Details
2. Glutathione S-transferase omega-1
General function:
Involved in glutathione transferase activity
Specific function:
Exhibits glutathione-dependent thiol transferase and dehydroascorbate reductase activities. Has S-(phenacyl)glutathione reductase activity. Has also glutathione S-transferase activity. Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA) and dimethylarsonic acid.
Gene Name:
GSTO1
Uniprot ID:
P78417
Molecular weight:
27565.6
Reactions
Methylarsonate + Glutathione → Methylarsonite + Oxidized glutathione + Waterdetails
Enzyme Details
3. Glutathione S-transferase omega-2
General function:
Involved in glutathione transferase activity
Specific function:
Exhibits glutathione-dependent thiol transferase activity. Has high dehydroascorbate reductase activity and may contribute to the recycling of ascorbic acid. Participates in the biotransformation of inorganic arsenic and reduces monomethylarsonic acid (MMA).
Gene Name:
GSTO2
Uniprot ID:
Q9H4Y5
Molecular weight:
24399.09
Reactions
Methylarsonate + Glutathione → Methylarsonite + Oxidized glutathione + Waterdetails
