^‡ The inclusion criteria followed three main requisites: (i) experimental detection of the proteins in the exoproteomes of the pathogenic C. diphtheriae and C. jeikeium; (ii) non-detection of the proteins in the exoproteomes of the non-pathogenic C. glutamicum and C. efficiens; and (iii) in silico detection of ortholog proteins in pathogenic, but not in non-pathogenic, corynebacteria through search of similarity against public protein repositories.
^a This protein list is not meant to be all-inclusive. Rather, it wants to give an overview of the exported proteins identified in this study for which it was possible to speculate on a probable involvement in C. pseudotuberculosis virulence after comparative proteomic analyses.
^b Proteins identified in this study by TPP/LC-MS^E
^c Searches of similarity against publicly available protein databases using Blast-p.
