Abstract excerpt
Aerobic growth of Escherichia coli sodAsodB and katE mutants lacking cytosolic superoxide dismutases and catalase hydroperoxidase II was inhibited by osmotic upshift to a greater extent than of their wild-type parent strains. The fur mutation leading to an intracellular overload of iron also increased sensitivity of growing E. coli cells to osmotic upshift. Using lacZ fusions, it was shown that expression of...
