, 2006 Proton-translocating ATPases synthesize or hydrolyze ATP coupling with electrochemical proton gradient, and have important roles in animal and plant physiology. The ion transporting ATPases are classified as F-ATPases (F-type ATPases), V-ATPases (V-type ATPases), and P-ATPases (P-type ATPase).

The nature of proton‐translocating ATPases in maize roots
Journal of Plant Nutrition, 1992Abstract The mechanisms of the coupling between ATP hydrolysis and proton transport catalyzed by the ATPases of the tonoplast and plasma membrane of maize (Lea mays L.) roots were investigated. Proton transport by the tonoplast ATPase was found to be much more sensitive to nitrate than ATP hydrolysis, being inhibited by 80% with almost no effect on ...

Homology between the α and β subunits of chloroplast and bacterial proton-translocating ATPases
FEBS Letters, 1984 The α and β subunits of tobacco chloroplast proton-translocating ATPase show 25% sequence homology. When these subunits from tobacco chloroplast and Escherichia coli are compared, 66 amino acid residues are identical and the majority of them are ...

Proton translocation by ATPase and bacteriorhodopsin.
Federation proceedings, 1977Stable membrane proteins and lipids are convenient to study biomembranes. Two stable proton translocating proteins were purified and reconstituted into vesicles capable of proton translocation. One was a thermostable ATPase (TF0-F1) of thermophilic bacterium PS3 and the other was rhodopsin of Halobacterium halobium. TF0-F1 was composed of a proton pump

The Proton-Translocating ATPase of Escherichia Coli
Annual Review of Biophysics and Biophysical Chemistry, 1990The purpose of this review is to provide an up-to-date summary of E. coli proton-translocating F1F0ATPase. From work on this enzyme, new insights have been gained in the areas of bacterial physiology and energy metabolism, mechanism of enzyme action, mechanism of ion transport through membranes, structure of membrane proteins, mechanism of energy ...

The plasma membrane proton-translocating ATPase
Cellular and Molecular Life Sciences, 2000Living cells require membranes and membrane transporters for the maintenance of life. After decades of biochemical scrutiny, the structures and molecular mechanisms by which membrane transporters catalyze transmembrane solute movements are beginning to be understood.

The proton-translocating ATPase of Candida tropicalis plasma membrane
Biochimie, 1982Proton translocation activity of Candida tropicalis plasma membrane ATPase has been demonstrated using a fluorescent delta pH probe (ACMA) and by direct pH measurements. Modifications in fluorescence intensity and H+ transport are highly specific for Mg2+ and ATP, and are sensitive to the well-known inhibitors of the plasma membrane ATPase, vanadate ...

Effect of diamide on proton translocation by the mitochondrial H+-ATPase
Biochemical and Biophysical Research Communications, 1985Treatment of sonic submitochondrial particles with the bifunctional thiol reagent, diamide, results in an enhancement of proton conductivity and ATPase activity, which is reversed by the reducing agent dithiothreitol, is suppressed by Fo inhibitors like oligomycin and is absent in particles that are deprived of peripheral Fo polypeptides. The effect of
