KEGG   ENZYME: 2.1.1.137
Entry
EC 2.1.1.137                Enzyme                                 

Name
arsenite methyltransferase;
S-adenosyl-L-methionine:arsenic(III) methyltransferase;
S-adenosyl-L-methionine:methylarsonite As-methyltransferase;
methylarsonite methyltransferase
Class
Transferases;
Transferring one-carbon groups;
Methyltransferases
Sysname
S-adenosyl-L-methionine:arsenite As-methyltransferase
Reaction(IUBMB)
(1) S-adenosyl-L-methionine + arsenite = S-adenosyl-L-homocysteine + methylarsonate [RN:R05755];
(2) S-adenosyl-L-methionine + methylarsonite = S-adenosyl-L-homocysteine + dimethylarsinate [RN:R05756]
Reaction(KEGG)
R05755 R05756
Substrate
S-adenosyl-L-methionine [CPD:C00019];
arsenite [CPD:C06697];
methylarsonite [CPD:C07295]
Product
S-adenosyl-L-homocysteine [CPD:C00021];
methylarsonate [CPD:C07294];
dimethylarsinate [CPD:C07308]
Comment
An enzyme of the biotransformation pathway that forms dimethylarsinate from inorganic arsenite and arsenate. It methylates arsenite to form methylarsonate, Me-AsO3H2, which is reduced by EC 1.20.4.2, methylarsonate reductase, to methylarsonite, Me-As(OH)2. Methylarsonite is also a substrate for this enzyme (EC 2.1.1.137), which converts it into the much less toxic compound dimethylarsinate (cacodylate), Me2As(O)-OH.
History
EC 2.1.1.137 created 2000, (EC 2.1.1.138 incorporated 2003), modified 2003
Orthology
