Fluorescent probes folding kinetics
WebThe folding kinetics of G-CSF were determined by trp-fluorescence and far-UV circular dichroism. Folding and unfolding was achieved by rapid dilution and mixing of the denaturant, GdnHCl. G-CSF is a four-helical bundle protein with two long loops between the first and second helices and between the third and fourth helices. WebAug 13, 2016 · The observation of wavelength-dependent folding kinetics, measured for λ 6-85, 165 revealed that the folding rate decreased with an increase in the degree of structural compaction, indicating that the protein folding energy landscape was rougher on the native than on the unfolded side of the activation energy barrier.
