Topography of a vacuolar-type H+-translocating ATPase: chromaffin-granule membrane ATPase I.

Proteins exposed on the cytoplasmic face of isolated chromaffin granules were labelled by lactoperoxidase-catalysed radioiodination and by non-enzymic biotinylation. Granule membranes were then prepared, and the H+-translocating ATPase isolated by fractionation with Triton X-114. The labelling of individual ATPase subunits was assessed by polyacrylamide-gel electrophoresis, followed by autoradi...

Structural organization of the yeast vacuolar H+-ATPase The yeast vacuolar proton-translocating ATPase

The yeast vacuolar proton-translocating ATPase (VATPase) is structurally very similar to the V-ATPases of other fungi, plants and animals (for reviews, see Stevens and Forgac, 1997; Forgac, 1999; Nelson and Harvey, 1999). In all these systems, the V-ATPase is composed of a complex of peripheral membrane proteins containing the ATP binding sites attached to a complex of integral membrane protein...

Renal vacuolar H+-ATPase.

Vacuolar H(+)-ATPases are ubiquitous multisubunit complexes mediating the ATP-dependent transport of protons. In addition to their role in acidifying the lumen of various intracellular organelles, vacuolar H(+)-ATPases fulfill special tasks in the kidney. Vacuolar H(+)-ATPases are expressed in the plasma membrane in the kidney almost along the entire length of the nephron with apical and/or bas...

H' ATPase of Chromaffin Granules

The chromaffin granule ATPase mediates an inwardly directed transport of H+ against concentration gradients, thereby forming and maintaining an electrochemical transmembrane H+ gradient. The kinetics of this ATPase, its activity modulation by changes in electrochemical H+ gradients, and the stoichiometry between H+ transport and ATP hydrolysis were studied in intact bovine chromaffin granules, ...

CopA: An Escherichia coli Cu(I)-translocating P-type ATPase.

The copA gene product, a putative copper-translocating P-type ATPase, has been shown to be involved in copper resistance in Escherichia coli. The copA gene was disrupted by insertion of a kanamycin gene through homologous recombination. The mutant strain was more sensitive to copper salts but not to salts of other metals, suggesting a role in copper homeostasis. The copper-sensitive phenotype c...
