Structural diversity of L pyocins. (A) Cartoon representation of PyoL1 from Pseudomonas aeruginosa C1433 (PDB 4LE7). (B) Structural model of PyoL2 from strain 62. Estimated accuracy of the model is 1.42 (C-score) with a template modeling score of 0.91 ± 0.06 and root mean square deviation of 3.0 ± 2.2 Å. (C) Cartoon-surface representations of the PyoL2 model. Residues constituting the D-rhamnose binding sites III^C and II^C are shown as blue and red spheres, respectively. Nonconserved residues differing between PyoL2 and PyoL1 are indicated in black. Conservative substitutions are not marked: V-M, E-Q, G-A, I-L, I-V, A-V, R-K, N-D, T-S.
