Adenosine triphosphatase in the phloem of Cucurbita
Planta, 1973The distribution of adenosine triphosphatase (ATPase) activity in the phloem of petioles and minor veins of Cucurbita maxima has been studied using a lead phosphate precipitation procedure. ATPase activity was localized in sieve elements, companion cells and parenchyma cells.

Thiamine triphosphatase in the nervous system
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1972Abstract Thiamine triphosphate is hydrolyzed by a specific triphosphatase in subcellular fractions of rat brain. This enzyme differs from nucleoside triphosphatases in (1) its subcellular distribution pattern; (2) its susceptibility to inhibition by Ca 2+ ; (3) its activation by sodium deoxycholate; (4) its failure to be affected by known inhibitors ...

The adenosine triphosphatase activity of the meromyosins
Biochimica et Biophysica Acta (BBA) - Enzymology, 1967Abstract 1. 1.|Mg 2+ does not activate the ATPase (ATP phosphohydrolase, EC 3.6.1.3) of actin-heavy meromyosin complex (acto-HMM) at low ionic strength. 2. 2.|The interaction inhibitor heparin, which dissociates actomyosin and inhibits its ATPase activity, also inhibits the ATPase of acto-HMM. 3.

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.

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

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.
