The Sosnick Group at The University of Chicago


The Sosnick Group strives to characterize the general principles that guide protein folding and dynamics. We combine multiple experimental and computational approaches to characterize the behavior of proteins in diverse contexts

Protein Folding - the 70% Rule

We have found that for many small 2-state proteins, the rate-limiting step of folding - the transition state - has ~70% of the native topology, according to the relative contact order.

Molecular Dynamics on your laptop!

Wouldn't it be nice to have physically realistic MD trajectories of protein dynamics without needing cpu-weeks/months of simulations? We have developed an MD engine that can reversibly fold some proteins up to 97 amino acids in cpu-days without requiring the use of fragments, homology or evolution.
