2′/3′-O-Acetyl ADP Ribose is produced as a metabolite from the sirtuin-mediated protein deacetylation of Nicotinamide adenine dinucleotide. Sirtuins, an ancient class of enzymes present in all organisms, first transfer acetate from Nε-acetyllysine residue to NAD. Water displaces nicotinamide and 2′/3′-O-Acetyl ADP Ribose is generated, rapidly equilibrating to a mixture of esters. Evidence suggests that 2′/3′-O-Acetyl ADP Ribose, as a mixture of the 2′- and 3′- isomers, functions as an intracellular second messenger. At neutral pH, the isomers of 2′/3′-O-Acetyl ADP Ribose exist in a ~1:1 ratio and are generated through a non-enzymatic fashion of intramolecular transesterification.
