Comparative Molecular Dynamics Analysis of RNase-S Complex Formation

Limited proteolysis of RNase-A yields a short N-terminal S-peptide segment and the larger S-protein. Binding of S-peptide to S-protein results in the formation of an enzymatically active RNase-S protein. S-peptide undergoes a transition from intrinsic disorder to an ordered helical state upon association with S-protein to form RNase-S and is an excellent model system to study coupled folding and binding. To better understand the dynamics of the RNases-S complex and its isolated partners, comparative molecular dynamics simulations have been performed.
