Metabolite Identification
Common Name6-Methylthiopurine 5'-monophosphate ribonucleotide
Description6-Methylthiopurine 5'-monophosphate ribonucleotide, also known as methylthioinosine-5'-monophosphate or meTIMP, is a metabolite of mercaptopurine. Mercaptopurine (also called 6-mercaptopurine, 6-MP, or its brand name Purinethol) is an immunosuppressive drug. Mercaptopurine is in the thiopurine and antimetabolite family of medications (Wikipedia). MeTIMP produced from 6-thioinosine monophosphate (6-TIMP) by thiopurine methyltransferase (TPMT) is an active metabolite that can inhibit de novo purine biosynthesis. High concentration of meTIMP has been related to hepatotoxicity and myelotoxicity (PMID: 21311411 ).

General function:
Involved in hypoxanthine phosphoribosyltransferase activity
Specific function:
Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway.
