Applications 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).

Applications A nucleotide of nicotinic acid which is produced from quinolinic acid by quinolinate phosphoribosyltransferase via transfer of a phosphoribose group. It is an intermediate of nicotinic acid adenine dinucleotide (NaAD) which is then converted to NAD via amidation and in turn converted to NADPH.
