Protein tyrosine O-sulfation is an essential post-translational modification required for effective biological processes such as hemostasis, inflammatory response, and visual phototransduction. Because of its unstable nature under mass spectrometry conditions and residing on low-abundance cell surface proteins, sulfated tyrosine (sulfotyrosine) residues are difficult to detect or analyze. Enrichment of sulfotyrosine-containing proteins (sulfoproteins) from complex biological samples are typically required before analysis. In this work, we seek to engineer t
