Abstract:
The interaction of cytochrome C with cystine as promoter was studied by synchronous fluorescence spectroscopy. After cystine was added into cytochrome C solution, the synchronous flurorescence spectra of tyrosine and tryptophan residues in cytochrome C were monitered with time. The results indicated that the lysine residues in cytochrome C molecules combine with cystine slowly. It induced the small conformational change of cytochrome C molecules.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
