15-136 5.74e-68

TonB system transport protein ExbD, group 1; Members of this family are Gram-negative bacterial inner membrane proteins, generally designated ExbD, related to the TolR family modeled by TIGRFAMs TIGR02801. Members always are encoded next to a protein designated ExbB (TIGR02797), related to the TolQ family modeled by TIGRFAMs TIGR02796. ExbD and ExbB together form a proton channel through which they can harness the proton-motive force to energize TonB, which in turn energizes TonB-dependent receptors in the outer membrane. TonB-dependent receptors with known specificity tend to import siderophores or vitamin B12. A TonB system and Tol-Pal system often will co-exist in a single bacterial genome.

15-135 2.04e-41

TolR protein; The model describes the inner membrane protein TolR, part of the TolR/TolQ complex that transduces energy from the proton-motive force, through TolA, to an outer membrane complex made up of TolB and Pal (peptidoglycan-associated lipoprotein). The complex is required to maintain outer membrane integrity, and defects may cause a defect in the import of some organic compounds in addition to the resulting morphologic. While several gene pairs homologous to talR and tolQ may be found in a single genome, but the scope of this model is set to favor finding only bone fide TolR, supported by operon structure as well as by score.
