A technique for the demonstration of myofibri1lar adenosine triphosphatase activity (A TPase) used for mammalian muscle has been modified to suit fish muscle. The mammalian method involves selectively inhibit...

Histochemical studies of adenosine triphosphatase activity of liver cells exposed to ribonuclease.

It has been revealed that ribonuclease (RNase) can penetrate into living cells and inhibits amino acid incorporation into proteins resulting in the suppreion of protein synthesis and growth of living cells. BHIDE, BRACHET, KAUFMAN and DAs have proven that the RNase penetrates into onion root-tip cells and induces a number of mitotic abnormalities. KIMOTO and others also have revealed that RNase...

Inhibition of Adenosine Triphosphatase Activity

Triphenylsulphonium ions inhibit mitochondrial oxidative phosphorylation and adenosine triphosphatase activity. The site of action is on the soluble F1 adenosine triphosphatase component. Triphenylsulphonium ions also inhibit electron transfer in the NAD-cytochrome b region of the respiratory chain. In both types of inhibition, triphenylsulphonium ions are effective at low concentrations, half-...

Sites of Adenosine Triphosphatase Activity in Bacteria.

Approximately 2 to 3 weeks of continuous cultivation were necessary before cells became persistently infected with rickettsiae. Although the detachment of cells from the glass surface became prominent during the third week of culture, no cytopathology specific to rickettsial multiplication was observable. Intracytoplasmic localization of the rickettsiae at the 12th transfer of infected FL cells...
