Tellurite methyltransferase (EC 2.1.1.265, TehB) is an enzyme with systematic name S-adenosyl-L-methionine:tellurite methyltransferase.[1][2] This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + tellurite S-adenosyl-L-homocysteine + methanetelluronate

The enzyme is involved in the detoxification of tellurite.
