Prolyl cis/trans isomerizations determine the rates of protein folding reactions and can serve as molecular switches and timers. In the gene-3-protein of filamentous phage, Pro-213 trans --> cis isomerization in a hinge region controls the assembly of the 2 domains N1 and N2 and, in reverse, the activation of the phage for infection. We elucidated the structural and energetic basis of this proline-limited domain assembly at the level of individual residues by real-time 2D NMR. A local cluster of ...[more]
