The S-peptide from ribonuclease S forms its α-helical structure only upon binding to the folded S-protein. We characterized the transition state for this binding-induced folding reaction at high resolution by determining the effect of site-specific backbone thioxylation and side-chain modifications on the kinetics and thermodynamics of the reaction, which allows us to monitor formation of backbone hydrogen bonds and side-chain interactions in the transition state. The experiments reveal that α-helical structure in the S-peptide is absent in the transition state of binding. Recognition between the unfolded S-peptide and the S-protein is mediated by loosely packed hydrophobic side-chain interactions in two well defined regions on the S-peptide. Close packing and helix formation occurs rapidly after binding. Introducing hydrophobic residues at positions outside the recognition region can drastically slow down association."}],"publication":"PNAS","publication_status":"published","doi":"10.1073/pnas.1012668108","author":[{"last_name":"Bachmann","first_name":"Annett","full_name":"Bachmann, Annett"},{"full_name":"Wildemann, Dirk","first_name":"Dirk","last_name":"Wildemann"},{"last_name":"Praetorius","id":"dfec9381-4341-11ee-8fd8-faa02bba7d62","full_name":"Praetorius, Florian M","first_name":"Florian M"},{"full_name":"Fischer, Gunter","first_name":"Gunter","last_name":"Fischer"},{"full_name":"Kiefhaber, Thomas","first_name":"Thomas","last_name":"Kiefhaber"}],"_id":"14305","keyword":["Multidisciplinary"],"pmid":1,"date_published":"2011-01-12T00:00:00Z","day":"12","year":"2011","publisher":"Proceedings of the National Academy of Sciences","article_type":"original","language":[{"iso":"eng"}],"intvolume":"       108","oa_version":"Published Version","issue":"10","title":"Mapping backbone and side-chain interactions in the transition state of a coupled protein folding and binding reaction","quality_controlled":"1","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.1073/pnas.1012668108","open_access":"1"}]}
