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

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).
