Arsenic

AS3MT, cyt19, arsenite methyltransferase, S-Adenosyl-l-methionine:arsenic(III) methyltransferase
AS3MT catalyzes the transfer of a methyl group from S-adenosyl-L-methionine (AdoMet) to trivalent arsenical and may play a role in arsenic metabolism (Lin et al., 2002 [PubMed 11790780]).[supplied by OMIM, Mar 2008] (from NCBI)
