Venn diagrams (generated byhttp://www.biovenn.nl/) showing the overlap between the samples generated by the different proteases used. Overlap between the different samples based on distinct protein accession (after accession sorting). A, before the selection strategy; B, after the selection strategy, found in each sample (both absolute numbers and fractions are shown). Overlap between the different samples based on distinct peptides found in each sample. C, before the filtering strategy (based on all identifications); D, after the filtering strategy (thus N-terminal peptides).
