Proteins co-immunoprecipitated with SIRT6 were analysed by MALDI-TOF Mass Spectrometry.

Mass spectra were collected and individual peptide ions were selected for fragmentation analysis by LIFT-MS/MS sequencing. Spectra were interpreted as described and the data searched against protein sequence databases using the Mascot programme. The table shows the detected ion, the corresponding peptide, the name and accession number of the protein in which that sequence is found and the Mascot E value reflecting confidence of the assignment. M = Methionine oxidised.
