John A. Ridge,* Robert L. Baldwin,* and Alexander M. Labhardt abstract: The fast and slow refolding reactions of iron (III) cytochrome c (Fe (III) cyt c), previously studied by Ikai et al.(Ikai, A., Fish, W. W „& Tanford, C.(1973) J. Mol. Biol.73, 165-184), have been reinvestigated. The fast reaction has the major amplitude (78%) and is 100-fold faster than the slow reaction in these conditions (pH 7.2, 25 C, 1.75 M guanidine hydrochloride). We showhere that native cyt c is the product formed in the fast reaction as well as in the slow reaction. Two probes have been used to test for formation of native cyt c: absorbance in the 695-nm band and rate of reduction by l-ascorbate. Different unfolded species (UF, Us) give rise to the fast and slow refolding reactions, as shown both by re-folding assays at different times after unfolding (“double-jump” experiments) and by the formation of native cyt c in (Cytochrome c (cyt c) 1 was the subject of the first systematic study, in modern terms, of the kinetics of a protein folding transition. After finding conditions for reversible unfolding and refolding, Ikai et al.(1973) analyzed the kinetics by the theory of Ikai & Tanford (1973), which assumes that only one form of the unfoldedprotein is present. They concluded that
