The Na + /K +-ATPase, a membrane-associated ion-motive ATPase, uses energy from the hydrolysis of ATP to move Na + out of and K + into cells. We have labeled ATPase isolated from duck supraorbital salt glands with one of Cy3-maleimide, and Alexa Fluor carboxylic acid, succinimidyl ester.
One of ion-regulating enzymes is classified as ion motive adenosine triphosphatase (ATPase). Ion motive ATPases exchange two different ions across the membrane at the expense of ATP energy.
ATPases involved in ion translocation are present in a diverse variety of biological membranes. Three major classes of these ‘ion motive’ enzymes, designated here as ‘P’ (phosphorylated), ‘V’ (vacuolar), and ‘F’ (F 0 F 1), are now known to exist.
In addition to the regulation of intracellular ionic or pH balance, some ATPases help drive numerous physiological or biological processes by ‘energy coupling’.Cited by: Amyloid beta-peptide impairs ion-motive ATPase activities: evidence for a role in loss of neuronal Ca2+ homeostasis and cell death These data suggest that impairment of ion-motive ATPases may play a role in the pathogenesis of neuronal injury in Alzheimer's disease.

New models of the gastric H,K ATPase in the E1K and E2P states are presented as the first structures of a K+ counter-transport P2-type ATPase exhibiting ion entry and exit paths.
Homology modeling was first used to generate a starting conformation from the srCa ATPase E2P form (PDB code 1wpg) that contains bound MgADP.
Energy minimization of the model showed a conserved adenosine site but Missing: Ion-Motive. These are two of a class of proteins called """""Ion-motive ATPases""""", enzymes that use the energy of ATP to pump ions across cell membranes.
Ion pumps play an important role in all cells, and disordered function of these enzymes is associated with human disease, including heart failure. The gastric hydrogen potassium ATPase or H + /K + ATPase is the proton pump of the stomach.
It exchanges potassium from the intestinal lumen with cytoplasmic hydronium  and is the enzyme primarily responsible for the acidification of the stomach contents and the activation of the digestive enzyme pepsin  (see gastric acid).Missing: Ion-Motive.
ion-motive ATPases in the anterior and posterior gills of D. pagei. We also provide electrophysiological data that support a role for apical V-ATPases in active, transbranchial Cl– uptake. Materials and methods Crabs Intermoult Dilocarcinus pagei Stimpson, measuring –cm carapace width, were collected from a temporary.
The present investigation examined the microanatomy and mRNA expression and activity of ion-motive ATPases, in anterior and posterior gills of a South American, true freshwater crab, Dilocarcinus pagei. Like diadromous crabs, the anterior gills of this hololimnetic trichodactylid exhibit a highly attenuated (2–5 μm), symmetrical epithelium on both lamellar surfaces.

However, the book does include coverage of subunit membrane architecture, on whichworkhas progressed nicely. Thefact that the V-type pumps function in vivo as true ATPases, unlike the F-type pumps, perhaps deserves more.
Welcome,you are looking at books for reading, The mediators of these fundamental processes are ion-motive ATPases, highly conserved enzymes that play key roles in cell physiology from bacteria to man. As the first comprehensive overview of this important class of enzymes, this handbook summarizes recent knowledge about the molecular.
This ATPase activity is generally the easiest way of identifying them. Pumps are membrane-embedded enzymes that couple the hydrolysis of ATP to active translocation of ions across the membrane.
The central issue of ion motive ATPases is to couple the hydrolysis of ATP (and their auto-phosphorylation) to the translocation of ions.

Price: $ There are P-type ATPases of different specificity with respect to the transported substrate(s). In animal cells, P-type ATPases are known for uniport, e.g., of Ca 2+ (review: Carafoli ) or H + (Kinne-Saffran ) and for antiport, e.g., of H + /K + (Forte et al. ) or of Na + /K + (Skou ), the latter being probably the most familiar Missing: Ion-Motive.
