^a: protein sequence identity (%) with the E. coli orthologous gene; ^b: genome sequence of BCt was not analysed systematically, we have only reported here the presence/absence of orthologous genes; ^c: proteomic data were compiled from [66], +/− (rank) indicates the presence/absence of the protein in partially purified samples of BAp (rank of the quantitative detection out of 400 proteins).
