Abstract

Poly and mono ADP-ribosylation activities occur in Euglena gracilis Z. The ADP-ribosylation activity changes depending on the stage of cell cycle in cells synchronized by a light-dark cycle and shows two different peaks: the first in the S phase and the other in the G2-M transition. The latter has about two times greater activity compared to the former. Poly ADP-ribosylation occurred only in the S phase. Mono ADP-ribosylation occurred in the S phase and the G2-M transition. ADP-ribosylation activity was found in the cytosol, mitochondria and chloroplasts and also showed a change in activity dependent upon cell division.
