Using high performance liquid chromatography, X-ray diffraction and Fourier transformation infrared spectra, the authors characterized the sorted proteins from different otoliths. It is found that the three types of proteins in lapillus and asteriscus have different characteristics, and such differences may be responsible for different kinds of crystalline state in calcium carbonate.

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.
