Name	Thiopurine or thiol or thiocyanate S-methyltransferase (TPMT).

Function

Thiol S-methyltransferase (EC 2.1.1.9) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to a thiol to form a thioether and S-adenosyl-L-homocysteine. Thiocyanate S-methyltransferase (EC 2.1.1.n4) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to thiocyanate to form methyl thiocyanate and S-adenosyl-L-homocysteine. Thiopurine S-methyltransferase (EC 2.1.1.67) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to a thiopurine to form methyl a thiopurine S-methylether and S-adenosyl-L-homocysteine.
