Biopolymer transport, TolR (IPR014168)

Short name: Biopolymer_transpt_TolR

Overlapping homologous superfamilies


Family relationships


This entry 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. While several gene pairs homologous to talR and tolQ may be found in a single genome, the members of this entry should be bone fide TolR, supported by operon structure.
