LC-MS/MS peptide map profile of N-terminal domain of Mo-MLV integrase monomer crosslinked gel band. Samples were digested overnight at 37°C with 0.8 μg of trypsin. The image shows the ionization and sequence of the LC peak (indicated in the inset) corresponding at the intramolecular peptide 96–105 and 86–95 with K88 and K104 modified.
