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.

Organization of Oligomycin-Sensitive Adenosine Triphosphatase

Biochemical Society Transactions, 1976
superaggregates 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.

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 ...

[63] Adenosine triphosphatase: Bacterial

1971
Publisher Summary The membrane fragments prepared from a variety of photosynthetic bacteria, when illuminated, can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate (P i ). Chromatophores prepared from the facultative photoheterotroph, Rhodospirillum rubrum , catalyze the hydrolysis of ATP into ADP ...

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.
