FIG. 3.

Alignment of the predicted amino acid sequences of BrnQ of S. aureus (Sa), BrnQ of B. subtilis (Bs), BraB of C. perfringens (Cp), BrnQ of L. delbrueckii (Ld), BrnQ of S. typhimurium (St), BraB of P. aeruginosa (Pa), BrnQ of E. coli (Ec), and BraZ of P. aeruginosa (Pa) by the Clustal W alignment program described by Thompson et al. (25). Identical amino acid residues are shown in boldface type, and similar amino acid residues are indicated by plus signs. The protein sequences were aligned by the insertion of gaps (—) to obtain maximum sequence identity. The following amino acids are similar: A, S, and T; D and E; N and Q; R and K; and I, L, M, V, F, Y, and W.
