It is an acyclic mixed acid anhydride, an adenosine 5'-phosphate and a pyridine nucleotide. It is functionally related to an adenosine 5'-monophosphate and a pyridinium-3,5-biscarboxylic acid mononucleotide. It is a conjugate acid of a 1-(5-O-phosphono-beta-D-ribofuranosyl)-5-(sulfanylcarbonyl)pyridinium-3-carbonyl adenylate(3-)."}]
