  • Title: The reconstitution of functional respiratory chains in membranes from electron-transport-deficient mutants of Escherichia coli as demonstrated by quenching of atebrin fluorescence.
    Author: Haddock BA, Downie JA.
    Journal: Biochem J; 1974 Sep; 142(3):703-6. PubMed ID: 4377217.
    Abstract:
    Measurements were made of electron-transport-dependent quenching of atebrin fluorescence in particles prepared from mutants of Escherichia coli unable to synthesize either ubiquinone or haem. Such quenching was either absent (in haem-deficient particles) or decreased (in ubiquinone-deficient particles), but was restored under conditions used to reconstitute oxidase activities. It is concluded that the reconstitution of oxidase activity, in both cases, is associated with the formation of a functional, proton-translocating, respiratory chain.
