The Lethal Effects of X-Irradiation and of Hydrogen Peroxide on Wild-Type and on a High-Catalase Mutant of Rhodopseudomonas spheroides
Data are presented te show that high levels of catalase in Rhodopseudomonas spberoides protect sgainst inactivation by added hydrogen peroxide but not against inactivation by x irradiation. The degree of protection against hydrogen peroxide is in good agreement with theoretical predictions. Oxygen enlances damsge by x irradiation but reduces damage caused by hydrogen peroxide diffusion into the cell. lt is concluded that diffusing hydrogen peroxide is not a major intermediate in radiation damage of these cells.
