  • Title: Mitochondrial adenosine triphosphatase of Zajdela hepatoma. III. Effect of uncouplers on the hydrolysis of intramitochondrial ATP.
    Author: Kolarov J, Kuzela S, Krempaský V, Ujházy V.
    Journal: Neoplasma; 1977; 24(6):649-51. PubMed ID: 201877.
    Abstract:
    Hydrolysis of extramitochondrial ATP by coupled Zajdela hepatoma mitochondria is not stimulated by uncouplers of oxidative phosphorylation. The results of the present study show that the hydrolysis of intramitochondrial ATP in these mitochondria is stimulated by DNP and CCCP. It is proposed that the uncoupler insensitivity of ATPase in coupled Zajdela hepatoma mitochondria with exogenous ATP as a substrate result from an altered functional relationship between ATPase and ADP, ATP translocase.
