Tyrosine sulfation, a post-translational modification, can enhance and often determine
protein-protein interaction specificity. Sulfotyrosyl residues (sTyr) are formed by tyrosylprotein
sulfotransferase during maturation in the golgi apparatus, and most often occur
singly or as a cluster of two or three sTyr within a six-residue span. With both negative
charge and aromatic character, sTyr enables numerous atomic contacts as visualized in
binding interfac...
