By using multi-dimensional nuclear magnetic resonance method we have studied the folding mechanism of staphylococcal nuclease in vitro; the tertiary interactions for folding of SNase fragments into native-like conformation; the interaction between SNase N- and C-terminal subunits; the relationship of enzyme activity with folding and dynamic states of SNase; the structural properties of enzyme protein while exert its function. We have studied the internal motions of thermophilic Archaea protein Ssh10b and mechanism of its heat-resistance using the NMR 1H-15N relaxation and H/D exchange methods. We have determined the 3D solution structure of human translationally controlled tumor protein TCTP and the Ca2+-binding site; determined the 3D crystal structure of human mitoNEET, a novel protein from distinct groups of iron-sulfur proteins; determined the 3D solution structure of a novel chromatin protein Cren7. Determination of SNase-DNA and Archaea protein-DNA complex structures are in progress.
