Abstract
The spectra of fluorescence of the tyrosyle-tRNA synthetase C-module have been obtained. The microsurrounding of a tryptophan residue has been characterized using the methods of fluorescence spectroscopy and computational modeling. The rapid conformation dynamics of the C-module in nanosecond time scale is revealed using the fluorescence quenching with acrylamide and Cs ions.
