Metabolite Identification
Common Name5'-Methylthioadenosine
Description5'-Methylthioadenosine (MTA) is a naturally occurring sulfur-containing nucleoside present in all mammalian tissues. It is produced from S-adenosylmethionine mainly through the polyamine biosynthetic pathway, where it behaves as a powerful inhibitory product. MTA is metabolized solely by MTA-phosphorylase, to yield 5-methylthioribose-1-phosphate and adenine, a crucial step in the methionine and purine salvage pathways, respectively. Evidence suggests that MTA can affect cellular processes in many ways. For instance, MTA has been shown to influence regulation of gene expression, proliferation, differentiation and apoptosis (PMID 15313459 ). 5-Methylthioadenosine can be found in animal urine. Elevated excretion appears in children with severe combined immunodeficiency syndrome (PMID 3987052 ).
