Figure 2

The rpsA TIRs of γ-proteobacteria (A–C) possessing the E.coli-like fold. Conserved sequence/structure elements are boxed. (A) Enterobacteria. The bases in the Sty_rpsA TIR differing from E.coli are circled. (B) Buchnera species, endosymbionts of Acyrthosiphon pisum (APS) and Schizaphis graminum (Sg). (C) Pasteurellaceae species with known rpsA sequences. Beside the wild-type Hin_rpsA TIR structure, a mutant variant with the Eco-ss1 inserted in between the hairpins I and II (Hin+Ecoss1_rpsA TIR) is shown.
