Normalized concentrations of peptides containing i amino acid monomers in the reaction mixtures with different concentrations of NaCl: experimental data (symbols) and theoretical fits (lines + symbols). The fit at z = 1.01 is the same for the CDI only and the CDI + 1.0M NaCl data.
Same as Fig. 1 but with KCl.
Ratios versus i at different concentrations of KCl and NaCl: experiment (symbols) and theory (lines + symbols).
Reaction scheme: (a) reversible activation of a peptide monomer with CDI; (b) irreversible reaction chain producing peptides A i (i = 1,2,3…).
Evolution of f i (z) at b = 1/2.
Fitting values of z, the estimated k + n tot t values, and the ratios of KCl to NaCl-catalyzed rate constants at different salt concentrations.
