as possible influences on cellular recovery following irradiation. The team showed that the most resistant bacterial species contained approximately 300 times more manganese and three times less iron than the most sensitive species. In the new study, which examined the functional consequences of this disparity, the researchers demonstrated that high cytosolic manganese and low iron concentrations enable resistance by protecting proteins, but not DNA, from IR-induced oxidative damage.
