Recent advances of thiol-selective bioconjugation reactions
WebOct 13, 2024 · Cysteine is special in the context of proteins, since cysteine residues often pair up via disulfide bonds, and this changes its properties. By itself, the -SH group is polar (although less so than an -OH group) so … WebCysteine residues can complicate proteolytic digestion, because of either disulfide scrambling or structural hindrance to proteolytic sites. Therefore, modification of cysteine residues by reduction and alkylation typically increases the efficiency and robustness of the proteolytic digestions. iphone 14 product life cycle
