This review gives an overview about the structural organisation of different evolutionary lines of all enzymes capable of… Expand Inorganic polyphosphate [poly(P)] levels in Escherichia coli were reduced to barely detectable concentrations by expression of… Expand Catalases are ubiquitous hydrogen peroxide-detoxifying enzymes that are central to the cellular antioxidant response. Of two… Expand A rapid spectrophotometric assay to determine the activities of HPI and HPII catalases in Escherichia coli extracts has been… Expand Pathogenic microorganisms possess antioxidant defense mechanisms for protection from reactive oxygen metabolites such as hydrogen… Expand BACKGROUND
Catalase is a ubiquitous enzyme present in both the prokaryotic and eukaryotic cells of aerobic organisms. It serves… Expand Catalase HPII from aerobically grown Escherichia coli normally contains heme d but cultures grown with poor or no aeration… Expand Chromosomal transcriptional and translational lacZ fusions to the katE (structural gene for the HPII hydroperoxidase) and katF… Expand Three strains of Escherichia coli differing only in the catalase locus mutated by transposon Tn10 were constructed. These strains… Expand A class of catalase-deficient mutants that was unlinked to katE was localized between mutS and cys at 59.0 min on the Escherichia… Expand
