Lire la suite >N-selenoethyl cysteine (SetCys) in the form of its cyclic selenosulfide is a cysteine surrogate, whose reactivity depends on the reducing power of the medium. SetCys does not interfere with the native chemical ligation reaction under mild reducing conditions, that is in the absence of tris(2-carboxyethyl)phosphine (TCEP). In contrast, subjecting SetCys to TCEP results in the spontaneous loss of its N-selenoethyl appendage and thus to its conversion into a Cys residue. Therefore, SetCys can be used for the redox-controlled assembly of peptide segments using NCL. We provide in this protocol detailed procedures for the synthesis of Fmoc-protected SetCys residue and for its incorporation into peptides using standard solid-phase peptide synthesis protocols. We also describe its use for the chemical synthesis of proteins through the redox-controlled assembly of three peptide segments in one-pot.Lire moins >
