摘要: Summary The occurrence of a membranal GTP-binding protein in Dictyostelium discoideum is described. found the membranes both vegetative and developing amoebae, has molecular weight approximately 42,000 serves as substrate for NAD + -dependent ADP-ribosylation, catalyzed by cholera toxin. resembles regulatory factor (“G protein”) vertebrate adenylate cyclase may play an analogous role D. .
