We describe here a general model of the kinetic mechanism of protein folding. In
the Foldon Funnel Model, proteins fold in units of secondary structures, which
form sequentially along the folding pathway, stabilized by tertiary interactions.
The model predicts that the free energy landscape has a volcano shape, rather
than a simple funnel, that folding is two-state (single-exponential) when
secondary structures are intrinsically unstable, and that each structure along
the folding path is a transition state for the previous structure. It shows how
sequential pathways are consistent with multiple stochastic routes on funnel
landscapes, and it gives good agreement with the 9 order of magnitude dependence
of folding rates on protein size for a set of 93 proteins, at the same time it is
consistent with the near independence of folding equilibrium constant on size.
This model gives estimates of folding rates of proteomes, leading to a median
folding time in Escherichia coli of about 5 s.
