Protein folding through kinetic discrimination – MC simulations of amyloid formation

If protein folding occurred through random search through all possible conformation it would take longer than the life time of the universe – the Levinthal paradox. Using Monte Carlo simulations we have shown that protein folding can occur within very limited CPU time based on random search (association kinetics governed by closeness in space and equal for all kinds of contacts)if there iskinetic discrimination among formed contacts (slower average dissociation rate for native compared to non-native contacts). We are extending our algorithm towards simulations of amyloid formation from peptides, and investigate factors like sequence changes and the origin of sigmoidity in kinetic data.
