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 bacteriumRhodospirillum rubrum and related bacteria. A dinitrogenase reductase ADP-ribosyltransferase (DRAT) and a dinitrogenase reductase ADP-ribose glycohydrolase (DRAG) fromR. rubrum have been isolated and characterized. The genes for these proteins have been… CONTINUE READING
