Specifically , the sirtuin - catalyzed AcK side chain deacetylation is not merely an amide hydrolysis reaction , instead is coupled to the nicotinamide cleavage from beta - nicotinamide adenine dinucleotide ( beta - NAD + or NAD + ) with the generation of three enzymatic products , i . e . the deacetylated protein species , nicotinamide , and 2 ' - O - acetyl - ADP - ribose ( 2 ' - O - AADPR ) .
