[Ability of yeast mitochondria to transport magnesium ions]. / O sposobnosti mitokhondrii drozhzhei transportirovat' iony magniia.

Endomyces magnusii mitochondria were shown to be incapable of active Mg2+ transport at 0.1--16 mM concentrations. As was found using the inhibition analysis, when magnesium ions are added to the mitochondria once the phosphorylation cycle is over, the respiration is stimulated because adenylate kinase and H+-ATPase (Mg2+-dependent enzymes) are activated.

[Induction of ion transport coupled to oxidative reactions in the membranes of mitochondria and liposomes]. / Induktsiia ionnogo transporta, sopriazhennaia s okislitel'nymi reaktsiiami v membranakh mitokhondrii i liposom.

The mechanism of induction of potassium permeability for mitochondrial membranes under special conditions was under study. Conditions were such as: 1--incubation of mitochondria in medium with low meaning of pH (6,0--6,5), 2--incubation in preseace of electrophylic agent--p-(N,N-di-2-chloroethyl) aminophenylacetic acid, which is hydrolized to HCl and 3-lipidsoluble acid, 2,4-dinitrophenol. It is shown that the named mechanism in any case requires the oxidation of lipids of mitochondrial membranes.
