High impact information on SPBC115.02c


Biological context of SPBC115.02c

  • I propose that the plasma membrane Mg2+-dependent ATPase in yeast cells not only carries out electrogenic H+ ejection but also drives the uptake of potassium via a voltage-sensitive gate which is closed in the absence and open in the presence of the membrane potential [6].
  • Electrogenic proton translocation coupled to ATP hydrolysis by the plasma membrane Mg2+-dependent ATPase of yeast in reconstituted proteoliposomes [7].
  • In the yeast Schizosaccharomyces pombe, the structural gene mutations A23-13 (alpha-) and B59-1 (beta-) which totally prevent the expression of either the alpha or the beta subunits of the mitochondrial ATPase, were shown by classical genetic mapping studies to be both located on chromosome I but genetically unlinked [8].
  • A close correlation is observed between the pH dependence of the intrinsic fluorescence and the pH dependence of (i) ATPase activity, (ii) the fluorescence of Tb-formycin triphosphate bound to the active site, and (iii) inhibition by vanadate of ATPase activity [9].
  • These results suggest that in these conditions, the target of Dio-9 is not the mitochondrial ATPase but a plasma membrane proton-translocating function generating an electrochemical gradient required for active transport [10].

Anatomical context of SPBC115.02c


Associations of SPBC115.02c with chemical compounds

  • In this report, we show that, as in the case of other P-type ATPase, the purified enzyme exhibits a p-nitrophenylphosphatase activity which can be completely inhibited by vanadate [16].
  • Two mutations involved a defective ATPase activity and the inability to grow on glycerol (gly) [8].
  • In the presence of antimycin A, specific mitochondrial ATPase inhibitors such as venruricidin A do not inhibit metabolite uptakes and their stimulation by adenosine 3':5'-monophosphate [10].
  • The phospholipid distribution in the sucrose gradient indicates that inactivation of the ATPase may result from the partial delipidation occurring during purification [17].
  • The mutant pma1-2 ATPase activity is markedly stimulated by 10-20% dimethyl sulfoxide, which has a limited effect on the wild type and pma1-1 enzymes [18].
