[Proton transfer from water to octane coupled with the reaction of ATP hydrolysis by soluble ATPase from chloroplasts].

It has been shown that soluble ATPase from chloroplasts adsorbed at the octane/water interface generates an ATP hydrolysis coupled potential charge (deltapi) at the interphase. This process occurs in the presence of a lipid-soluble proton acceptor, in the capacity of which 2,4-dinitrophenol is used. The dependence of deltapi, generated by ATPase, on the concentration of the enzyme. ATP and dinitrophenol, has been studied.

[Iso-octane soluble complex of cytochrome c with bovine brain phospholipids].

The conditions are determined for formation of the isooctane-soluble complex of cytochrome c with bull brain phospholipids. Molecular ratio protein/lipid in lipocytochrome c is 1 : 20 divided by 30. Ferri- and ferroforms of protein have different affinity to phospholipids. The ferrocytochrome c in the complex is subjected to self-oxidation in the absence of redox agents. Interaction of protein with phospholipids in water phase is shown to be of electrostatic nature. The cytochrome c conformation in water solution and in the complex does not differ significantly. But the mode of packing of lipid and protein molecules in the isooctane-soluble complex depends upon the degree of oxidation as has been shown by sedimentation methods. Cytochrome c maintains his conformation in a complex with phospholipids and retains the ability to redox reactions.
