  • Our research is concerned with structural and dynamical aspects of protein function. We are interested in elucidating correlation between structure, dynamics and biological functions of macromolecular proteins. To pursue our goals, we use nuclear magnetic resonance spectroscopy (NMR). The NMR method targets solution proteins under various conditions, included in living cells. Therefore, it allows us to obtain crucial information for elucidating biological functions of proteins at an atomic resolution. Although NMR is powerful tool, its potential has been limited due to the presence of signal broadening, overlapping and lower sensitivity in large molecular weight proteins (ex. > 25 kDa). To overcome this problem, various isotope labeling techniques were developed. Our individual techniques, Stereo array isotope labeling (SAIL) method contributed significantly to improve NMR spectra of larger proteins and succeeded in determining precise structure of 42 kDa proteins. For much larger proteins and protein complexes (i.e. > 50 kDa), presently, we use site specific amide (15NH) and methyl (13CH3) labeling methods. Although it allows us to obtain highly sensitive methyl and amide TROSY signals that enable the study of local structure, it's still not sufficient for NMR-based structure determination which is needed for understanding precise protein function. In order to solve this problem, we have been developing the new SAIL amino acids. Our new SAIL methods allow us to observe the several 1H-13C signals even in 80-1000 kDa large molecular proteins. This information is very useful for understanding the precise structure and dynamic property of various macromolecular proteins such as membrane proteins and protein-protein complexes.
