Sequence alignment of the bacterial β-clamps with determined crystal structures. Drβ-clamp short, Mycobacterium tuberculosis (Mtβ-clamp; Gui et al., [7]), Streptococcus pneumoniae clamp (Spnβ-clamp; unpublished, PDB code 2AWA), Streptococcus pyogenes clamp (Spyβ-clamp; Argiriadi et al., [6]), Thermotoga maritima clamp (Tmβ-clamp; unpublished, PDB code 1VPK), and Ecβ-clamp (Kong et al., [5]). Stars denote the positively charged Drβ-clamp residues facing the inside of the ring, and triangles indicate hydrophobicity pocket residues. The figure was prepared with ESPript 3.0 [24].
