Figure 2.

Histrograms of protein sequence coverage. A histogram of the sequence coverage of the S. cerevisiae ORFs by PeptideAtlas (darker filled bars) and an in silico tryptic digestion of the reference protein database with a mass range of 500 to 4,000 Da (lighter diagonal pattern filled bars) is shown. Of the PeptideAtlas ORFs, 61% have coverage below 20%, while 39% have a coverage above 20%.
