Tellurite methyltransferase explained

Tellurite methyltransferase
Ec Number:	2.1.1.265

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

\rightleftharpoons S-adenosyl-L-homocysteine + methanetelluronate

The enzyme is involved in the detoxification of tellurite.
