Adenosine triphosphatase in the phloem of Cucurbita

Planta, 1973
The 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.

The adenosine triphosphatase activity of the meromyosins

Biochimica et Biophysica Acta (BBA) - Enzymology, 1967
Abstract 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, 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.

Structure of the Vacuolar Adenosine Triphosphatases

Cell Biochemistry and Biophysics, 2001
Vacuolar 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.

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.

Intermediate states of actomyosin adenosine triphosphatase

Biochemistry, 1976
The early kinetic steps of actomyosin subfragment 1 (acto-S1) adenosine triphosphatase have been investigated by simultaneous monitoring of fluorescence and light scattering and also by observation of the time course of the production of phosphate. The results show that fluorescence enhancement occurs after the dissociation of actomyosin and that the ...

Adenosine triphosphatase and morphological integrity of mitochondria

Biochimica et Biophysica Acta, 1957
Abstract Gramicidin, antimycin A, dinitrophenol, and butyl-3,5-diiodo-4-hydroxybenzoate stimulate mitochondrial ATPase at 23° without causing swelling of these particles. Desoxycholate, saponin, and triiodothyroacetic acid activate ATPase at 23° but also produce swelling or rupturing of the mitochondria. Triiodothyronine, thyroxine, stearic acid, and
