Influence of Growth Medium on Assimilatory Activities of Escherichia Coli.
Clifton, C. E. (Stanford University, Stanford, Calif.). Influence of growth medium on assimilatory activities of Escherichia coli. J. Bacteriol. 85:1371-1377. 1963.-Nutrient agargrown cells assimilate about 50% of the glucose added to washed suspensions (phosphate buffer, pH 7.2, 30 C), as indicated by O(2) consumption or C(14)-uptake from uniformly labeled glucose. Most of the nonassimilated g...
متن کاملPpra: an Important Protein of Radiation Resistance in Deinococcus Stimulates Catalase Activity in Escherichia Coli
Deinococcus radiodurans is characterized by its exceptional capacity to tolerate the effects of various DNA damaging agents due to presence of the extraordinary DNA repair mechanism. DNA double strand break repair in Deinococcus radiodurans follows biphasic kinetics. The phase I, a RecA independent phase appears to be a DNA protective and preparatory phase for RecA dependent phase II repair. Pp...
متن کاملIron uptake by Escherichia coli.
Ferric iron is transported into Escherichia coli by a number of chelating compounds. Iron transport through the outer membrane by citrate, ferrichrome, enterobactin, aerobactin, yersiniabactin, and heme is catalyzed by highly specific proteins and across the cytoplasmic membrane by ABC transport systems with lower specificity. Transport across the outer membrane requires energy, which is provid...
متن کاملRpoS- and OxyR-independent induction of HPI catalase at stationary phase in Escherichia coli and identification of rpoS mutations in common laboratory strains.
A rapid spectrophotometric assay to determine the activities of HPI and HPII catalases in Escherichia coli extracts has been developed. This assay is based upon the differential heat stabilities of the two enzymes and offers significant advantages over previous methods for quantitation of their activities. Measurement of catalase activities in extracts of various mutant strains confirmed the ab...
متن کاملActivity, peroxide compound formation, and heme d synthesis in Escherichia coli HPII catalase.
Wild-type Escherichia coli HPII catalase (heme d containing) has 15% the activity of beef liver enzyme per heme. The rate constant for compound I formation with H2O2 is 1.3 x 10(6) M(-1) s(-1). HPII compound I reacts with H2O2 to form O2 with a rate constant of 1.8 x 10(6) M(-1) s(-1). Forty percent of HPII hemes are in the compound I state during turnover. Compound I is reduced by ethanol and ...
