    BHMT-2 methyltransferase catalyzes the transfer of a methyl group from S-methylmethionine to L-homocysteine, yielding two molecules of L-methionine. In this study, we have prepared the first series of BHMT-2 inhibitors to be described, and we have tested them with human recombinant BHMT-2 that has been stabilized by copurification with human recombinant BHMT. Among the compounds synthesized, (2S,8RS,11RS)-5-thia-2,11-diamino-8-methyldodecanedioic acid was the most potent (Ki app about 77 nM) and selective inhibitor of BHMT-2. This compound may be useful in future in vivo studies to probe the physiological significance of BHMT-2 in sulfur amino acid metabolism.
