FIG 1.
(A and B) Alignment of ExbD43–141 and TonB33–239 affinity-selected Ph.D.-C7C and Ph.D.-12 peptides to the ExbD sequence. (A) The top 10 scoring ExbD43–141 affinity-selected peptides aligned to residues 46 to 73 of the periplasmic domain of ExbD. See also Table S1 in the supplemental material for peptide match scores and window sizes. (B) The top nine scoring TonB33–239 affinity-selected peptides aligned to residues 46 to 62 of the periplasmic domain of ExbD. See also Table S2 in the supplemental material for peptide match scores and window sizes. (C and D) Alignment of ExbD43–141 affinity-selected Ph.D.-C7C and Ph.D.-12 peptides to TonB sequence. (C) The top six scoring peptides aligned to residues 38 to 55 of the periplasmic domain of TonB. (D) The top nine scoring peptides aligned to residues 125 to 144 of the central region of periplasmic TonB. See also Table S3 in the supplemental material for peptide match scores and window sizes. Only top-scoring peptides are shown for clarity; see the corresponding tables in the supplemental material for all peptides.
