  • Title: Inhibition of the soluble adenosine triphosphatase from mitochondria by adenylyl imidodiphosphate.
    Author: Philo RD, Selwyn MJ.
    Journal: Biochem J; 1974 Dec; 143(3):745-9. PubMed ID: 4376952.
    Abstract:
    1. Adenylyl imidodiphosphate is an inhibitor with high affinity for the soluble ATPase (adenosine triphosphatase) from mitochondria. 2. The reaction of the inhibitor with the ATPase is slow and estimates for the association and dissociation reaction rate constants are given. 3. The number of binding sites for the inhibitor appears to be doubled in the presence of 2,4-dinitrophenol. 4. Adenylyl imidodiphosphate is less effective as an inhibitor of the ATPase activity of this enzyme than of the inosine triphosphatase activity. It is also less effective on the ATPase of frozen-thawed or intact mitochondria and did not inhibit ADP-stimulated respiration by intact mitochondria.
