  • Title: In vivo evidence for the role of the epsilon subunit as an inhibitor of the proton-translocating ATPase of Escherichia coli.
    Author: Klionsky DJ, Brusilow WS, Simoni RD.
    Journal: J Bacteriol; 1984 Dec; 160(3):1055-60. PubMed ID: 6238948.
    Abstract:
    The function of the epsilon subunit of the Escherichia coli proton-translocating ATPase has been examined by using a mutant defective in the uncC gene. Strains with a defective uncC gene show a reduction in both growth yield and growth rate that is more severe than for other unc mutants; this deleterious effect is shown to be a result of the ATPase activity of the F1 complex which is missing the epsilon subunit. In addition, the epsilon-deficient F1 is bound less tightly to the membrane. These data suggest that, in vivo, the epsilon subunit is capable of inhibiting the ATPase activity of F1 and also functions in the binding of F1 to F0.
