Abstract
Several cases of ADP-ribosylation of endogenous proteins in procaryotes have been discovered and investigated. The most thoroughly studied example is the reversible ADP-ribosylation of the dinitrogenase reductase from the photosynthetic bacterium Rhodospirillum rubrum and related bacteria. A dinitrogenase reductase ADP-ribosyltransferase (DRAT) and a dinitrogenase reductase ADP-ribose glycohydrolase (DRAG) from R. rubrum have been isolated and characterized. The genes for these proteins have been isolated and sequences and show little similarity to the ADP-ribosylating toxins. Other targets for endogenous ADP-ribosylation by procaryotes include glutamine synthetase in R. rubrum and Rhizobium meliloti and undefined proteins in Streptomyces griseus and Pseudomonas maltophila.Entities:
