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.

The Mitochondrial Adenosine Triphosphatase

1982
In 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 ...

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.

[25] Membrane-bound thiamine triphosphatase

1979
Publisher 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

[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 ...

Model Reaction for Mitochondrial Adenosine Triphosphatase

Nature, 1968
THE soluble adenosine triphosphatase (ATPase) from mitochondria1–3 is activated by several bivalent metal ions, and the pattern of activation is essentially the same whether the enzyme is acting on ATP (Fig. 1) or ITP (Fig. 2). It is clear that the ionic radius is the chief factor determining the ability of a bivalent ion to activate this enzyme.
