CXMS analyses of BSA protein cross-linked with NHSF or BS2G. (A) Total number of identified cross-linked peptides from BS2G or NHSF cross-linked BSA. (B) Types of cross-linking sites identified from the NHSF cross-linked BSA sample, with numbers indicated on top. (C) Distribution of Cα-Cα distance of cross-linked residues from BSA samples. (D) Identified cross-links mapped onto the crystal structures of BSA (Protein Data Bank ID code 3V03). The Cα-Cα distances of cross-links are color-coded.
