Modification of proteins by mono(ADP-ribosylation) in vivo. 1985

D M Payne, and E L Jacobson, and J Moss, and M K Jacobson

We have pursued the detection of in vivo modified, ADP-ribosylated proteins containing N-glycosylic linkages to arginine. ADP-ribosylated histone, elongation factor 2, and transducin, containing the different known ADP-ribosylated amino acids (arginine, diphthamide, and cysteine, respectively), were employed as model conjugates to establish conditions for the selective detection of adenosine(5')diphosphoribose (ADP-ribose) residues bound to arginine. We report here the detection and quantification of protein-bound ADP-ribose residues in adult rat liver with linkages characteristic of arginine. These mono(ADP-ribose) residues were present in vivo at a level of 31.8 pmol/mg of protein which is 400-fold higher than polymeric ADP-ribose residues. A minor fraction (23%) of the ADP-ribose residues detected were bound via a second, more labile linkage with chemical properties very similar to those described for carboxylate ester linked ADP-ribose.

D006898	Hydroxylamines	Organic compounds that contain the (-NH2OH) radical.
D000246	Adenosine Diphosphate Ribose	An ester formed between the aldehydic carbon of RIBOSE and the terminal phosphate of ADENOSINE DIPHOSPHATE. It is produced by the hydrolysis of nicotinamide-adenine dinucleotide (NAD) by a variety of enzymes, some of which transfer an ADP-ribosyl group to target proteins.
