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 recruited to cell division sites and is required to maintain outer membrane integrity; defects may cause a defect in the import of some organic compounds. TolR is related to MotB, the peptidoglycan (PG)-binding stator protein from the flagellum, suggesting it might serve a similar role in Tol-Pal [PMID: 26354441].
