Metabolite Identification
Common NameMethylarsonate
DescriptionMethylarsonate is used as a contact herbicide in either the monosodium or disodium salt form. It goes by the trade names Weed-E-Rad, Ansar 170 H.C., Ansar 529 H.C., DiTac and others. Methylarsonate is considered only slightly toxic, having an oral LD50 of 2200 mg/Kg for rats. The inhalation risk is greater with LD50 Rats >20 mg. Long term studies with people exposed to organoarsenicals has shown an increased risk of skin cancer (Spiewak, 2001), lung cancer and some liver cancers, although some recent studies have shown some arsenic containing compounds (specifically Arsine trioxide) may have anticarcinogenic properties (Wang, 2001). In mammals, Methylarsonate is also an intermediate in the detoxification of inorganic arsenic. In the arsenate detoxification I pathway, arsenite reacts with S-adenosyl-L-methionine to produce methylarsonate and S-adenosyl-L-homocysteine. Arsenite methyltransferase catalyzes this reaction. Methylarsonate then reacts with 2 glutathione molecules to produce glutathione disulfide and methylarsonite. This reaction is catalyzed by methylarsonate reductase. Methylarsonate is an organic arsenic compound with adverse effects similar to those of arsenic trioxide. Arsenic is found in the environment primarily as arsenate and arsenite species. Arsenate is reduced to arsenite by arsenate reductase and can be subsequently methylated to Methylarsonate. This is then reduced and methylated to Dimethylarsinate, which can excreted and is considerably less toxic to the organism than any of the previous intermediate compounds. Methylarsonate was formerly included in some vitamin and mineral preparations. It was once used to treat tuberculosis, chorea, and other affections in which the cacodylates were used.

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 + Arsenite → S-Adenosylhomocysteine + Methylarsonatedetails
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:

Gene Name:
GSTO2
Uniprot ID:
Q9H4Y5
Molecular weight:
24399.09
Reactions
Methylarsonate + Glutathione → Methylarsonite + Oxidized glutathione + Waterdetails
