ADP-Ribosylation of Proteins in Non-infected Escherichia coli Cells

Abstract
Partially purified enzymatic fractions from extracts of E. coli B/r catalyze transfer of the isotope label from [adenine-2,8-3H]NAD+ to some bacterial proteins, as well as to hen egg white lysozyme. The radioactive group in the modified lysozyme was identified as mono(ADP-ribose). Several bacterial proteins were labeled in vivo with 32P; the presence of the label in the form of an ADP-ribosyl group was shown in one of them.
