Diseases of Renal Adenosine Triphosphatase
The American Journal of the Medical Sciences, 1995Most 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 ...

Deoxyuridine triphosphatase in human hepatoma
International Journal of Biochemistry, 19941. Deoxyuridine triphosphatase (dUTPase) in human hepatoma was investigated. The apparent activity in a gram weight tissue was about 6 times that of the activity in rat livers after partial hepatectomy. 2. Most catalytic properties of the hepatoma dUTPase were similar to the enzymes from other sources. 3.

Pharmacogenetic Significance of Inosine Triphosphatase
Pharmacogenomics, 2007Inosine triphosphatase (ITPase) is the enzyme that catalyzes the conversion of inosine triphosphate (ITP) and deoxy-inosine triphosphate (dITP) to inosine monophosphate and deoxy-inosine monophosphate, respectively, thereby maintaining low intracellular concentrations of ITP and dITP.

Structure of the Vacuolar Adenosine Triphosphatases
Cell Biochemistry and Biophysics, 2001Vacuolar adenosine triphosphatases (V-ATPases) represent an important class of proton pumps found in endomembrane systems of eucaryotic cells, where they are involved in pH regulation. Progress has been made in the structure determination of this large, membrane-bound multisubunit enzyme complex.

Adenosine triphosphatase distribution in mammary tissue [PDF]
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

Azasteroids and heart adenosine triphosphatase
Biochemical Pharmacology, 1966Abstract 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.

The Mitochondrial Adenosine Triphosphatase
1982In the previous chapter we saw that the ATPase activity of coupled mitochondria is dramatically stimulated by uncouplers and more generally by conditions that interrupt the flow of energy from the electron transfer chain to the coupling device. These observations have for a long time been interpreted to indicate that the ATPase is involved in the ...

Organization of Oligomycin-Sensitive Adenosine Triphosphatase
Biochemical Society Transactions, 1976superaggregates to an active tetramer of 360000daltons and a slow phase of half-time 15s representing the subsequent dissociation of tetramer to an inactive dimer. When enzyme at the same concentration is mixed with 5m-ATP, only the rapid phase of tetramer production is observed.
