5′-Deoxy-5′-(methylthio)adenosine (Methylthioadenosine) may be used as a substrate to study the specificity and kinetics of 5′-methylthioadenosinephosphorylase (MTAP) (EC2.4.2.28), a tumor suppressor gene expressed enzyme that supports the S-adenosylmethionine (AdoMet) and methionine salvage pathways. Methylthioadenosine is used in studies on bacterial quorum sensing pathways that envolve enzymes such as 5′-Methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN).
