Title	Tyrosine/Lysine-Targeting Urazole Cross-Linkers for Protein Structural Analysis
Description	Chemical cross-linking mass spectrometry (XL-MS) is essential for studying protein structures and interactions. While lysine-targeted cross-linkers dominate current applications, this study introduces two urazole-derived MS-cleavable cross-linkers for tyrosine and lysine residues. A homobifunctional cross-linker (SBT) targets tyrosine via electrochemical click chemistry, while a heterobifunctional cross-linker (SCT) binds both lysine and tyrosine. Their efficiency was validated through reactions with peptides, proteins, and complexes. Additionally, AlphaFold 3-predicted BSA dimer structures were compared with crystallographic data, revealing improved structural coverage. These cross-linkers expand the XL-MS toolkit, enhancing protein structural analysis accuracy and scope.
