LC-MS/MS peptide map profile of N-terminal domain of Mo-MLV integrase monomer crosslinked gel band digested with trypsin. (A), in the sample the peak corresponds to the peptide 86–105 with two cross-linked lysines (K88 and K95). (B), the peak corresponds at the peptide 25–34 with intramolecular cross-linked between K31 and K33, (C) in the monomeric sample the peak corresponds at the peptide 89–105 with intramolecular cross-linked between K95 and K104.
