The interest of the Laboratory is focused on studying structure, functions and regulation of yeast mitochondria, as well as on elucidation of their role in general cellular metabolism and apoptosis and on mechanisms of photoprotection and thermostability of cyanobacterial photosystems.
The main achievements:
1. A concept was advanced on models of yeast energy metabolism and the “economic feasibility” of energy metabolism under growth limitations. Specific features of energization of yeast mitochondria have been revealed. For the first time established that yeast mitochondria isolated from obligate aerobes possess full-functional respiratory chain with all three point of energy conservation, the finely regulated system for Ca2+ for transport and the ATP-dependent K+-channel of “animal type” (inhibited by ATP). They are have lost Ca2+-dependent cyclosporine-sensitive nonspecific permeability transition (pore). Graded oxidative stress was found to induce fragmentation of mitochondria and apoptosis, the fragmentation of mitochondria can be prevented and reversed (shown for the first time) by mitochondria-targeted antioxidants.
2. A unique osmo-, salt- and pH-tolerant strain of Yarrowia lipolytica was isolated and used for the first examination of the Na+-coupled yeast phosphate transport system and its regulation.
3. Topography of the active center of dicarboxylate transporter of rat liver mitochondria was studied by using derivatives of malonic acid. A hypothesis was put forward explaining the mechanism of transporter functioning. A dicarboxylate transporter of the plasma membrane of Saccharomyces cerevisiae yeast was revealed in the first time.
4. We investigated the changes caused by the reorganization of photosynthetic apparatus during transition from state 2 to state 1. It was shown that two processes affect the PSII activity during changes of light conditions: (1) reversible inactivation of PSII, which is associated with the reduction of electron carriers on PSII acceptor side in the dark, and (2) PSII activation under low light related to the increase in the functional absorption cross-section at 590 nm.
5. The pathways of energy dissipation of the excessively absorbed energy in cyanobacteria in comparison with that in higher plants were studied. It was shown that long wavelength chlorophylls affect weakly energy equilibration within the heterogeneous PSI antenna, but they significantly delay energy trapping by P700.
6. The role of High light-inducing HliA/HliB stress proteins of cyanobacteria ( the evolutionary ancestor of plant light-harvesting proteins) in the photoprotection of photosynthetic apparatus was studied. The association of HliA/HliB proteins not only with PS1 trimers, but also with PS1 monomers is shown, which suggests a universal role of these proteins in the protection of the photosynthetic apparatus from excess light.
7. Mechanisms of thermostability of cyanobacterial photosystems. Our data suggest differences in the arrangement of α-helices in monomers and trimers of PSI. The α-helices in monomers are more susceptible to temperature elevation than the respective α-helices in trimers. Therefore we propose that oligomerization is one of strategies to increase thermostability of PSI complexes. The trimerization of PSI monomers may induce structural changes that shield some parts of the PSI monomers which are sensitive to denaturation, thereby increasing the thermostability of PSI trimers.
