Abstract
Composition and cell localisation of ADP-ribosyltransferase C3 substra tes were studied in squid photoreceptors and in bovine ROS. Polypeptid es with M(r) 22, 24, 30, 45 and 80 kDa are ADP-ribosylated in squid ph otoreceptor membranes, and polypeptides with M(r) 22, 24, and 60 kDa a re ribosylated in cattle ROS membranes. Cytoplasmic fraction of ROS co ntains C3 substrates with M(r) 22, 24, 28 and 36 kDa. Increase in ADP- ribosylation of 22 and 24 kDa substrates and their interaction with ph otoexcited rhodopsin in squid photoreceptors was found.
