Microsecond Barrier-Crossing Collapse in Cytochrome c Folding Revealed by Two-Dimensional Fluorescence Lifetime Correlation Spectroscopy

Protein folding is initiated with a volume contraction called collapse. While the microsecond collapse of horse cyt c has been intensely studied, its molecular mechanism remains elusive. To characterize the structural change, we prepared three cyt c variants labeled with a fluorescent dye at distinct sites (D50, A83,...
