Adenosine triphosphatase distribution in mammary tissue
The Histochemical Journal, 1978Lactating 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, 1979Anaesthetic 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.

[63] Adenosine triphosphatase: Bacterial
1971Publisher 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 ...

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.

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.

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 ...

Adenosine triphosphatase of mycobacteria.
Microbios, 1980A Mg+2-(Ca+2)-activated adenosine triphosphatase activity has been demonstrated in saprophytic, human pathogenic and non-pathogenic, and atypical, species of mycobacteria. (Na+ + K+)-activated adenosine triphosphatase was absent in the species investigated.

[Mimosa pudica adenosine triphosphatase].
Biokhimiia (Moscow, Russia), 1978The morphological structure (pulvinus P1, P2 and P3) directly involved in the seismonastic movements of the Mimosa pudica leaf have been used to isolate: 1) "soluble" ATPase, loosely bound to pulvinus structures; 2) Ca, Mg-dependent ATPase, which is tightly bound to pulvinus structures and is extracted by a saline solution of high ionic strength, used ...
