WebMar 1, 2024 · Overview. Disulphide (S–S) bonds, i.e. the covalent crosslinks between thiol groups of two cysteine residues, are recognized means of stabilizing native and folded proteins ().Such disulphide crosslinks are known to entropically destabilize the unfolded states of a polypeptide, limit the mobility and thereby increase the stability of the folded …
WebThe reversible thiol-disulfide exchange reaction is particularly important in biological systems.In this S N 2, one-step, bimolecular reaction there is a nucleophilic Cys (a thiolate) that attacks a sulfur atom of a disulfide bond.
