The Unique Chemistry of Cysteine in Peptides

The defining characteristic of cysteine containing peptides is the sulfur atom within the thiol group. This sulfur atom is highly reactive and can participate in several crucial chemical transformations. One of the most significant is the formation of disulfide bonds, which are covalent linkages between two cysteine residues. These disulfide bridges are vital for stabilizing the three-dimensional structure of many peptides and proteins, contributing to their overall stability and function. Cysteine-rich peptides, for instance, heavily rely on these disulfide bonds for their structural integrity2015年8月6日—I have recently synthesised some short (around 20mer)peptides containingbetween 2 and 4 cysteines but I can't seem to dissolve them..

Beyond disulfide bond formation, the thiol group of cysteine can undergo various modifications, making cysteine containing peptides highly amenable to chemical functionalization. This includes S-alkylation, where the thiol group reacts with alkyl halides, a process explored for creating modified peptides with specific properties. Lipidation of cysteine or cysteine-containing peptides is another area of interest, involving the attachment of fatty acid chains to the cysteine residue, which can alter the peptide's solubility and membrane interactions. Furthermore, novel synthetic strategies are emerging, such as one-pot desulfohalogenation of cysteine-containing peptides, which converts cysteine thiols into electrophilic carbon-halogen bonds, opening avenues for new chemical transformations.^ "Nomenclature and symbolism for amino acids andpeptides(IUPAC-IUB Recommendations 1983)". ...
