Kinetic data for the refolding/unfolding of wt-ub and (4R)-FPro-ub monitored by changes in Tyr fluorescence using GdmCl denaturant.

Experiments were performed in 10 mM Gly/HCl buffer at pH 2.0 and at 25°C. Rate-constants and m-values listed were determined by globally fitting folding/unfolding rate constants and equilibrium fluorescence signals to a three-state on-pathway mechanism as described in material and methods.
aRate constants have units s−1.
bm-values have units kJ·mol−1·M−1.
cΔGun calculated using −RT ln(Kui(kin/kni)); units are kJ·mol−1.
dαTS1 is defined as mui/(mui+miu).
eαTS2 is defined as min/(min+mni).
