[Comparison of the effects of some perminductors on mitochondria and chloroplasts].

The effects of valinomycin, gramicidins A and S, melittin and the protonophore 3,5-di-tert-butyl-4-hydroxybenzylidenmalononitrile on rat liver mitochondria and pea chloroplasts during active electron transport were studied. The canalogenes melittin and gramicidin S as well as gramicidin A and the protonophore increase the proton conductance of the inner mitochondrial membrane and chloroplast tylakoid membrane. The curve for the dependence of the canalogene effects on their concentration is S-shaped for both types of the organelles.
