Protein bands submitted to MALDI-ToF MS analysis. Supernatant proteins were separated by SDS-PAGE and stained with colloidal Coomassie G. The indicated protein bands present in the wild type were excised and analysed by MALDI-ToF MS fingerprinting. Protein band missing in the culture supernatant of the prsD mutant (A898) are indicated by red arrows.
