Carbon and energy metabolism of atp mutants of Escherichia coli
TLDR
Data are interpreted as indicating that E. coli makes use of its ability to respire even if it cannot directly couple this ability to ATP synthesis; by respiring away excess reducing equivalents E. Escherichia coli enhances substrate level ATP synthesis.
Precise determinations of C and D periods by flow cytometry in Escherichia coli K-12 and B/r.
TLDR
Flow cytometric determinations of cell cycle periods confirm earlier determinations about the C period and establish that the D period also varies with generation time in slowly growing cultures, and extend the range of growth rates at which cell Cycle periods have been determined in E. coli K-12.
Hemin Reconstitutes Proton Extrusion in an H+-ATPase-Negative Mutant ofLactococcus lactis
TLDR
Inverted membrane vesicles prepared from hemin-grown L. lactis cells are capable of coupling NADH oxidation to proton translocation, suggesting that hemin complements proton extrusion.
Detection of Bacteriophage-Infected Cells of Lactococcus lactis by Using Flow Cytometry
TLDR
A new method for detection of phage infection in Lactococcus lactis dairy cultures is described, based on flow cytometric detection of cells with low-density cell walls, which allows fast and early detection ofphage-infected bacteria, independently of which phage has infected the culture.
Control analysis of the dependence of Escherichia coli physiology on the H(+)-ATPase.
The H(+)-ATPase plays a central role in Escherichia coli free-energy transduction and hence in E. coli physiology. We here investigate the extent to which this enzyme also controls the growth rate,
The Extent to Which ATP Demand Controls the Glycolytic Flux Depends Strongly on the Organism and Conditions for Growth
TLDR
It is suggested that the extent to which ATP demand controls the glycolytic flux depends on how much excess capacity of gly colysis is present in the cells.
Membrane integration and function of the three F0 subunits of the ATP synthase of Escherichia coli K12.
Integration into the cytoplasmic membrane and function of the three F0 subunits, a, b and c, of the membrane‐bound ATP synthase of Escherichia coli K12 were analysed in situations where synthesis of
Excess capacity of H(+)‐ATPase and inverse respiratory control in Escherichia coli.
TLDR
In E.coli, growth yield per O2 decreased, suggesting significant leakage or slip at the high respiration rates and membrane potential found at low H(+)‐ATPase concentrations, and explaining that growth yield may be increased by activating the H(+‐ ATPase.
Proton conduction by subunit a of the membrane‐bound ATP synthase of Escherichia coli revealed after induced overproduction.
Transcriptional fusions between the phage lambda promotor pR and ATP synthase genes, atp, on plasmid pBR322 were constructed in order to study the effects upon growth and physiology of Escherichia
