Abstract excerpt

The discovery of superoxide dismutase (CuZnSOD) within the periplasms of several Gram-negative pathogens suggested that this enzyme evolved to protect cells from exogenous sources of superoxide, such as the oxidative burst of phagocytes. However, its presence in some non-pathogenic bacteria implies that there may be a role for this SOD during normal growth conditions. We found that sodC, the gene that encodes the...
