Accession numbers from TrEMBL, Swiss-prot (bold), or GenPept (italic) databases. When two different types of protein with the same annotation were identified as reference sequences in the databases, homologous CDS were arbitrarily distinguished by superscript letters (a and b). For each strain harbouring one of these genes, the CDS with the most significant E-values is indicated by the corresponding superscript letter.
