Diseases of Renal Adenosine Triphosphatase

The American Journal of the Medical Sciences, 1995
Most renal transport is a primary or secondary result of the action of one of three membrane bound ion translocating ATPase pumps. The proximal tubule mechanisms for the reabsorption of salt, volume, organic compounds, phosphate, and most bicarbonate reabsorption depend upon the generation and maintenance of a low intracellular sodium concentration by ...

Viral adenosine triphosphatase

Experientia, 1978
The catalytic and immunological properties of an adenosine triphosphatase from different types of virus have been studied. The avian myeloblastosis virus has been found to be specialized in holding this enzyme in a highly active state as compared to other virus with respect to their host cell enzyme.

Brain capillary guanosine triphosphatase: A distinction from adenosine triphosphatase

Experientia, 1980
Differences in kinetic properties, pH response, sensitivity to ouabain, and disc-acrylamide electrophoresis resolution, are observed when GTP and ATP are used as the substrates for triphosphohydrolases in isolated rat brain microvessels. In brain parenchyma there are no such differences.

Azasteroids and heart adenosine triphosphatase

Biochemical Pharmacology, 1966
Abstract Azasteroids, some known to be active, others to be inactive as inotropic and antishock agents, were tested as inhibitors of a metal-stimulated heart ATPase. In every instance the biologically active azasteroids inhibited catalysis just as did ouabain and the erythrophleum alkaloids.

Adenosine triphosphatase distribution in mammary tissue

The Histochemical Journal, 1978
Lactating mammary tissue from farm animals and small mammals was perfusion-fixed, prior to histochemical procedures, in an effort to localize the ouabain-sensitive Na+/K+-stimulated ATPase enzyme with the use of specific inhibitors. Histochemical evidence suggests that the Na+/K+-stimulated ATPase is located predominantly on the cytoplasmic side of the

Barbiturates and calcium-activated adenosine triphosphatase

Neuroscience Letters, 1979
Anaesthetic barbiturates potentiate and convulsant barbiturates inhibit the calcium-activated adenosine triphosphatase (Ca-ATPase) activity in rat brain synaptosomes. Such differential effects and consequent modification of transmitter release may be important in the contrasting actions of these classes of barbiturates in vivo.

Tritiated Digoxin Binding to (Na+ + K+)-Activated Adenosine Triphosphatase: Possible Allosteric Site

Science, 1968
Tritiated H3-digoxin specifically binds to a cardiac (Na+ + K+)-activated adenosine triphosphatase. In the presence of adenosine triphosphate and other nucleoside di- and triphosphates, binding is stimulated by sodium ion, the apparent rate constant ...
