FIGURE 1.

Sequence alignment of the six outer membrane factor (OMF) proteins with known structures. Only the N- and C-terminal portions of the alignment (extract from Supplementary Figure S1) corresponding to the most divergent 3D structure regions of these OMF proteins are shown. The numbering corresponds to the OprM sequence after cleavage of the targeting signal presented in grey letters. The secondary structure of OprM is indicated at the top of the aligned sequences. The red brackets indicate the beginning and end of each protein resolved PDB structure.
