Abstract In the presence of diphtheria toxin, the adenosine diphosphate ribose portion of nicotinamide adenine dinucleotide was transferred to aminoacyl transferase II obtained from rat liver. The reaction resulted in a concurrent inactivation of this particular enzyme, one of the supernatant factors which assemble amino acids into polypeptide chain. The linkage of ADP-ribose to aminoacyl transferase II appeared to be of covalent nature. The reaction was reversible. Diptheria toxin may act as an enzyme or a catalytic cofactor in this reaction.
