Abstract in another language

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 inter-domain hydrogen bonds, remote from Pro-213, is stabilized up to 3,000-fold by trans → cis isomerization. This network of hydrogen bonds mediates domain assembly and is connected with Pro-213 by rigid backbone segments. Thus, proline cis/trans switching is propagated in a specific and directional fashion to change the protein structure and stability at a distant position.
