Fig. 5

Predicted OipA structure at its full-length. (a) shows the backbone with the top and bottom cross-sections, the ‘’FWHLA’’ pentamer is colored red. (b) Surface view of the predicted structure with hydrophobic residues shown in pink. (c) Structural superimposition of OipA (pink), SabA (blue) and BabA (brown). Β-barrel domain of all three structure were aligned and Cα RMSD values for both superimpositions were as follows for the pruned atoms: OipA-SabA: 0.897 Å, OipA-BabA: 0.915 Å
