The plasma membrane of Schizosaccharomyces pombe contains an H(+)-ATPase similar to the cation transport ATPases of other eukaryotic organisms. The fluorescence excitation and emission spectra of the purified H(+)-ATPase are characteristic of tryptophan residues. pH reduction from 7.5 to 5.7 produces a 4% decrease in fluorescence intensity, while a further reduction to pH 5.0 leads to an increase of fluorescence. A close correlation is observed between the pH dependence of the intrinsic… CONTINUE READING
