Brain Na+, K+-ATPase activity In aging and disease
(Master Publishing Group, 2014-07)
Na+/K+ pump or sodium- and potassium-activated adenosine 5’-triphosphatase (Na+, K+-ATPase), its enzymatic version, is a crucial protein responsible for the electrochemical gradient across the cell membranes. It is an ion ...
Na+ ATPase activities in chela muscle of the euryhaline crab Neohelice granulata: Differential response to environmental salinity
(Elsevier Science, 2009-04)
The occurrence and characteristics of ouabain-insensitive Na+ ATPase activity and the response to environmental salinity of the coexistent Na+-K+ ATPase and ouabain-insensitive Na+ ATPase activities were studied in chela ...
Toluene permeabilization differentially affects F- and P-type ATPase activities present in the plasma membrane of Streptococcus mutans
(Associação Brasileira de Divulgação Científica, 2008)
Streptococcus mutans membrane-bound P- and F-type ATPases are responsible for H+ extrusion from the cytoplasm thus keeping intracellular pH appropriate for cell metabolism. Toluene-permeabilized bacterial cells have long ...
Nantenine and papaverine differentially modify synaptosomal membrane enzymes
(Urban & Fischer Verlag, 2000-07-01)
Papaverine (1-[(3,4-Dimethoxyphenyl) methyl]-6,7-dimethoxyisoquinoline) and nantenine (O-methyldomesticine) are chemically related isoquinoline alkaloids displaying similar dose-dependent sedative or convulsant effects, ...
Na+, K+-ATPase and Ca2+-ATPase activities in basal and microvillous syncytiotrophoblast membranes from preeclamptic human term placenta
(Informa Healthcare, 2015)
Objective: The aim of this study is to evaluate the effect of preeclampsia on the level of lipid peroxidation, activity and expression of both plasma membrane Ca2+- and Na+, K+-ATPases in syncytiotrophoblast. Methods: The ...

(Informa Healthcare, 2015)
© Informa Healthcare USA, Inc.Objective: The aim of this study is to evaluate the effect of preeclampsia on the level of lipid peroxidation, activity and expression of both plasma membrane Ca2+- and Na+, K+-ATPases in ...
Kinetic Analysis of Gill (Na+,K+)-ATPase Activity in Selected Ontogenetic Stages of the Amazon River Shrimp, (Decapoda, Palaemonidae): Interactions at ATP- and Cation-Binding Sites
(Springer, 2012-04-01)
We investigated modulation by ATP, Mg2+, Na+, K+ and NH4 (+) and inhibition by ouabain of (Na+,K+)-ATPase activity in microsomal homogenates of whole zoeae I and decapodid III (formerly zoea IX) and whole-body and gill ...

Kinetic characterization of a membrane-specific ATPase from rat osseous plate and its possible significance on endochondral ossification
(Elsevier B.V., 1998-01-05)
Treatment with phosphatidylinositol-specific phospholipase C of rat osseous plate membranes released up to 90-95% of alkaline phosphatase, but a specific ATPase activity (optimum pH = 7.5) remained bound to the membrane. ...
