Thioether protein crosslinks
Thioether bonds between cysteine and tyrosine have been well studied in cysteine dioxygenases[1]. Thioether bonds between cysteine and the vinyl groups of hemes are common. Diverse other ligands are bonded to protein via cysteine thioether linkages.
An accurate estimate of the frequency of thioethers in the PDB may not be available. A search for "thioether" in Proteopedia yields >200 hits in abstracts of pages titled with 4-character PDB codes.
