New Integrated Structural Biology article: “Formation of a translocation competent protein complex by a dynamic wrap-around binding mechanism.”

This paper from the Wolf-Watz lab describes the discovery of a fundamentally new mechanism underlying protein-protein interactions. The chaperone-binding domain of the Yersinia effector protein YopH was found to lose its globular structure upon formation of a wrap-around architecture with its chaperone SycH. The mechanism is best described as a coupled binding and disordering event. The finding was enabled by an integrated structural biology approach by a five-lab effort and centered on NMR, SAXS and computational chemistry.

The article is published in Journal of Molecular Biology (2018), 430, 3157.
