Fig. 3

Histograms of the isoelectric points of proteins. Top and middle panels are calculated using the IPC_protein pKa set (in 0.25 pH unit intervals) and represents pI distribution in the SwissProt database, human proteome, Escherichia coli and extreme halophilic archaeon Natrialba magadii. Bottom two panels presents the isoelectric points of the yeast proteome (6,721 proteins) calculated using the EMBOSS pKa set (as presented in the Saccharomyces Genome Database [40]) and the IPC_protein pKa set for comparison
