Table 1. Number of unique features and peptides identified in the discovery phase.

Data filtering Number of entries for all 1680 proteins identified in the discovery phase Number of entries for GroEL
aDetected using the SuperHirn algorithm (Mueller et al, 2007).
bIdentified by database searching. FDR was set to 1%.
cPTPs are defined as features that assigned peptide sequences show full tryptic cleavage, contain no modification and only match to one protein sequence in the database used.
dUp to the five most intense PTPs per protein were selected for screening phase.
