Cysteine post-translational modification
WebCysteine represents an attractive handle for the introduction of such chemical modifications, as it is the second least frequent amino acid in proteins (1.7%) (6) and shows a very strong inherent nucleophilicity, which makes it especially attractive for reactions with electrophilic reagents. WebEmerging data demonstrates that transcription factors (TFs) are a main target of cysteine thiol-based oxidative post-translational modifications (OxiPTMs), which can alter …
