MALDI-MS and MS/MS data were combined through the BioTools 3.0 program (Bruker Daltonik, Bremen, Germany) to search the NCBInr (~107 entries; National Center for Biotechnology Information, Bethesda, US) or the Prokaryotes EST (~9x[10.sup.3] entries; National Center for Biotechnology Information) protein databases using the Mascot software (Matrix Science, London, UK) (Perkins et al., 1999).
