2.1.1.137	coenzyme M	-	733740	
2.1.1.137	dimethylselenoxide	weak activator of recombinant As(III)-methyltransferase, weak inhibitor of arsenite methylation in hepatocytes	658442	
2.1.1.137	dithiothreitol	-	485152, 733740	
2.1.1.137	dithiothreitol	weak activation	485148	
2.1.1.137	glutathione	-	485152	
2.1.1.137	glutathione	1 mM GSH decreases Km and increases Vmax estimates for arsenite and methylarsonous acid	721075	
2.1.1.137	glutathione	a 4fold increase in glutathione concentration, 2 to 8 mM, leads to a 2fold increase in enzyme activity, reducing environment is required for enzyme activity	485148	
2.1.1.137	glutathione	ArsM is able to methylate As(III) in the presence of Cys without glutathione. In contrast, ArsM is not able to methylate As(III) in the presence of tris(2-carboxyethyl)phosphine without GSH	757684	
2.1.1.137	glutathione	As(III) SAM methyltransferase conducts three successive rounds of oxidative methylation, with the glutathione conjugates serving as metalloid donors to the enzyme	718946	
2.1.1.137	glutathione	GSH should combine with the enzyme after the methylation to reduce the disulfide bond formed during the catalytic cycle to resume the active form of the enzyme	719007
