Proton translocation driven by ATP hydrolysis in V‐ATPases
FEBS Letters, 2003 The vacuolar H+‐ATPases (or V‐ATPases) are a family of ATP‐dependent proton pumps responsible for acidification of intracellular compartments and, in certain cases, proton transport across the plasma membrane of eukaryotic cells. They are multisubunit complexes composed of a peripheral domain (V1) responsible for ATP hydrolysis and an integral domain ...

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Localization of a Proton-Translocating ATPase on Sucrose Gradients [PDF]
Plant Physiology, 1982 Ionophore-stimulated ATPase activity and ATP-dependent quinacrine quench were enriched in parallel when microsomal vesicles were prepared from corn (Crow Single Cross Hybrid WF9-Mo17) roots and collected on a cushion of 10% dextran. Activities were highest in the apical 1.5 centimeters of the roots.

Estimating the Rotation Rate in the Vacuolar Proton-ATPase in Native Yeast Vacuolar Membranes [PDF]
, 2012 The rate of rotation of the rotor of the yeast vacuolar proton-ATPase (V-ATPase), relative to the stator or the steady parts of enzyme, is estimated in native vacuolar membrane vesicles of Saccharomyces cerevisiae under standardised conditions.

The microbiologist’s guide to membrane potential dynamics [PDF]
, 2020 All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

Electrogenic Proton Translocation by the ATPase of Sugarcane Vacuoles [PDF]
Plant Physiology, 1985 Existence of a proton-translocating ATPase on the tonoplast of higher plants has been further confirmed by use of two experimental systems: (a) intact isolated vacuoles from sugarcane cells and (b) vesicles prepared from the same source. Addition of MgATP to vacuoles polarized the tonoplast by 40 millivolts to a value of +20 millivolts, but a large ...

A cell-based assay for CD63-containing extracellular vesicles [PDF]
, 2019 Extracellular vesicles (EVs) are thought to be important in cell-cell communication and have elicited extraordinary interest as potential biomarkers of disease. However, quantitative methods to enable elucidation of mechanisms underlying release are few.

Proton translocation induced by ATPase activity in chloroplasts [PDF]
FEBS Letters, 1970 Proton uptake by chloroplasts was induced by light‐triggered ATPase activity. A quotient of two was obtained when the initial rate of proton uptake was divided by the rate of Pi released from ATP. Gramicidin accelerated the rate of ATPase activity and reduced the H+/Pi ratio to 1.4. The results were found to be consistent with the chemiosmotic theory.
