Abstract

The folding of some proteins appears to be a two-state kinetic process. A two-state kinetic model is justified if protein molecules rapidly equilibrate between different unfolded conformations prior to complete folding. Here I show that this rapid equilibration is a natural consequence of reasonable assumptions about reaction rate constants and folding thermodynamics.
