We discovered that this goal can be achieved in a traceless manner during ligation by appending a simple <em>N<\/em>-selenoethyl group to cysteine. While in synthetic organic chemistry the cleavage of carbon-nitrogen bonds is notoriously difficult, we found that <em>N<\/em>-selenoethyl cysteine (SetCys) loses its selenoethyl arm in water under mild conditions upon reduction of its selenosulfide bond. Detailed mechanistic investigations uncover a novel mode of reactivity for Cys. Its implementation in a process enabling the modular and straightforward assembly of backbone cyclized polypeptides is illustrated by the synthesis of biologically active cyclic hepatocyte growth factor mimics.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><em>Article highlighted by the Editors of Nature Communications.<\/em><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><a href=\"https:\/\/www.nature.com\/articles\/s41467-020-16359-6\">Link to the article<\/a><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"782\" height=\"233\" src=\"https:\/\/mint-team.fr\/wp-content\/uploads\/2024\/02\/SetCys.jpg\" alt=\"\" class=\"wp-image-627\" style=\"width:700px\" srcset=\"https:\/\/mint-team.fr\/wp-content\/uploads\/2024\/02\/SetCys.jpg 782w, https:\/\/mint-team.fr\/wp-content\/uploads\/2024\/02\/SetCys-300x89.jpg 300w, https:\/\/mint-team.fr\/wp-content\/uploads\/2024\/02\/SetCys-768x229.jpg 768w\" sizes=\"(max-width: 782px) 100vw, 782px\" \/><\/figure><\/div>","protected":false},"excerpt":{"rendered":"<p>The control of cysteine reactivity is of paramount importance for the synthesis of proteins using the native chemical ligation (NCL) reaction.
