Cytochrome c oxidase activity was demonstrated in 2 species of the giant amoeba Pelomyxa, one of which is radioresistant and the other radiosensitive. The differences observed in this enzyme do not appear to be sufficient to account for the 10-fold difference in radiosensitivity of the living organisms. The level of cytochrome c oxidase activity is about one-fortieth that of mammalian liver, and is highly labile at room temperature. The radioresistant Amoeba proteus was also assayed for cytochrome c oxidase activity but almost negligible amounts were found. (auth)
