Abstract: Effects of the absence of Cu,Zn-superoxide dismutase (CuZnSOD) on the replicative life span of the yeast Saccharomyces cerevisiae were studied under different oxygen conditions. In both strains, replicative life span and the rate of cell divisions were found to be similar under the atmosphere of air and under hypoxic (3% oxygen) and anoxic conditions. These results indicate that deleterious consequences of the lack of CuZnSOD are not limited to elevation of superoxide concentration and involve function(s) other than superoxide scavenging.
