[Study of interaction between cytochrome C and cystine using synchronours fluorescence spectroscopy].
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.
