Acid-base transport by the renal distal nephron
(WICHTIG EDITORE, 2010)
The functional versatility of the distal nephron is mainly due to the large cytological heterogeneity of the segment. Part of Na(+) uptake by distal tubules is dependent on Na(+)/H(+). exchanger 2 (NHE2), implicating a ...
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 ...
Oxidative damage to sarcoplasmic reticulum Ca2+-ATPase at submicromolar iron concentrations: Evidence for metal-catalyzed oxidation
(Pergamon-elsevier Science LtdOxfordInglaterra, 1998)
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 ...
Activation of H+-ATPase by glucose in Saccharomyces cerevisiae involves a membrane serine protease
(Elsevier Science, 2013-03)
Background: Glucose induces H+-ATPase activation in Saccharomyces cerevisiae. Our previous study showed that (i) S. cerevisiae plasma membrane H+-ATPase forms a complex with acetylated tubulin (AcTub), resulting in inhibition ...
P-type proton ATPases are involved in intracellular calcium and proton uptake in the plant parasite Phytomonas francai
(Soc ProtozoologistsLawrenceEUA, 2005)
Physiological implications of the regulation of vacuolar H+-ATPase by chloride ions
(Associação Brasileira de Divulgação Científica, 2009)
Vacuolar H+-ATPase is a large multi-subunit protein that mediates ATP-driven vectorial H+ transport across the membranes. It is widely distributed and present in virtually all eukaryotic cells in intracellular membranes ...
Effects of ammonia stress in the Amazon river shrimp Macrobrachium amazonicum (Decapoda, Palaemonidae)
(Elsevier B.V., 2016-01-01)
We evaluate the effects of total ammonia nitrogen-N (TAN) exposure for 72 h on (Na+,K+)- and V(H+)-ATPase activities and on their subunit expressions in gills of the diadromous freshwater shrimp Macrobrachium amazonicum. ...
Acid tolerance mediated by membrane ATPases in Lactobacillus acidophilus
(Springer, 2001-12)
The acid tolerance response in Lactobacillus acidophilus CRL 639, induced at pH 4.2 for 15 min, is mediated by the cell membrane F1-F0 ATPase. The specific activity of the enzyme was induced 1.6-fold after acid adaptation ...
Plasma Membrane H+-ATPases: Key Regulators of Plant Physiology
(Nova Science Publishers, 2020)
Plasma membrane H+-ATPases(PM-H+-ATPases) areimportant ion pumps in the plant cell membrane that play key roles in plant physiology. They extrude protons outof the cell, generating a membrane potential that provides the ...
