Regulation of proton-translocating V-ATPases [PDF]
Journal of Experimental Biology, 1997 ABSTRACT Vacuolar-type ATPases (V-ATPases) are proton-translocating enzymes that occur in the endomembranes of all eukaryotes and in the plasma membranes of many eukaryotes. They are multisubunit, heteromeric proteins composed of two structural domains, a peripheral, catalytic V1 domain and a membrane-spanning Vo domain.

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 ...

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.

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 ...

Evolutionary primacy of sodium bioenergetics
Biology Direct, 2008 Background The F- and V-type ATPases are rotary molecular machines that couple translocation of protons or sodium ions across the membrane to the synthesis or hydrolysis of ATP.

Cell Reports, 2017 Vacuolar H+-ATPase (v-ATPase) is a multi-subunit complex comprising two domains: the cytosolic V1 domain catalyzing ATP hydrolysis and the membranous V0 sector translocating protons across membranes.

Cryo-EM studies of the rotary H+-ATPase/synthase from Thermus thermophilus
Biophysics and Physicobiology, 2019 Proton-translocating rotary ATPases couple proton influx across the membrane domain and ATP hydrolysis/synthesis in the soluble domain through rotation of the central rotor axis against the surrounding peripheral stator apparatus.
