Metabolite Identification
Common NameDimethylarsinic acid
DescriptionDimethylarsinic acid, also known as cacodylic acid, is formally rated as possibly a carcinogenic (IARC 2B), potentially toxic compound. Derivatives of cacodylic acid, cacodylates, were frequently used as herbicides. For example, Agent Blue, one of the chemicals used during the Vietnam War, is a mixture of cacodylic acid and sodium cacodylate. Sodium cacodylate is frequently used as a buffering agent in the preparation and fixation of biological samples for transmission electron microscopy. Dimethylarsinic acid is highly toxic by ingestion, inhalation, or skin contact. Once thought to be a byproduct of inorganic arsenic detoxification, it is now believed to have serious health consequences of its own. It has been shown to be teratogenic in rodents, most often causing cleft palate but also fetal fatality at high doses. It has been shown to be genotoxic in human cells, causing apoptosis and also decreased DNA production and shorter DNA strands. While not itself a strong carcinogen, dimethylarsinic acid does promote tumours in the presence of carcinogens in organs such as the kidneys and liver (Wikipedia ).

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).
