Tpmt thiopurine methyltransferase

SpletThiopurine methyltransferase (TPMT) metabolizes the cytotoxic drug 6-mercaptopurine which is widely used in treatment of childhood acute lymphoblastic leukemia (ALL). This enzyme also metabolizes thioguanine, another anti-cancer drug, and azathioprine, a 6-mercaptopurine precursor which is used as an immunosuppressant. Splet03. apr. 2000 · Thiopurine methyltransferase (TPMT) catalyses the S-methylation of thiopurines, including 6-mercaptopurine and 6-thioguanine.
