Definition: An acetyl ester of ADENOSINE DIPHOSPHATE RIBOSE formed during NAD-dependent deacetylation of proteins by SIRTUINS. The acetate group resides on the ribose ring where nicotinamide was cleaved from NAD during the reaction. Several isomers of O-acetyl-ADP-ribose have been isolated from the reaction.
Other names O-Acetyl- Adenosine-Diphosphate-Ribose; O Acetyl Adenosine Diphosphate Ribose; O Acetyl ADP Ribose; Adenosine Diphosphate Ribose, O Acetyl; O-Acetyl-Adenosine-Diphosphate-Ribose; AADPR; Adenosine-Diphosphate-Ribose, O-Acetyl
