    摘要: The invention provides methods and compositions for protein structure analysis, including substrate binding sites, sites of protein-protein interactions, three dimensional structure analysis, and stability, all with single amino acid resolution. In general, the subject methods involve introduction of cysteine residues, which serve as probes for physical analysis, into a protein by translational misincorporation in vivo. In many embodiments, proteins containing misincorporated cysteine residues are reacted with a crosslinking agent that covalently links misincorporated cysteine residues to a proximal amino acid in the folded protein. These methods, termed “MXLINK” methods, may be used for protein tertiary structure analysis. In other embodiments, cysteine-misincorporated proteins are used in protein footprinting methods, termed “MPAX” or “MSX” methods.
