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 ...

A Simplified Preparation for Adenosine Triphosphatase Determination in Gill Tissue
, 1982A simplified preparation from gill tissue that yields adenosine triphosphatase activities comparable to some microsomal fractions is described. The procedure uses two short (6 and 7 min), low speed (2000 Relative Centrifugal Force) centrifugations at ...

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.

Adenosine triphosphatase and morphological integrity of mitochondria
Biochimica et Biophysica Acta, 1957Abstract 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

[25] Membrane-bound thiamine triphosphatase
1979Publisher Summary This chapter discusses membrane-bound thiamine triphosphatase. Thiamine triphosphate (ThTP) is present in significant quantities in most organisms, although its specific role in the cellular economy is unknown. Involvement of this compound in the function of excitable membranes has been postulated, but this hypothesis as yet remains
