CC -!- FUNCTION: Part of the Tol-Pal system, which plays a role in outer
CC membrane invagination during cell division and is important for
CC maintaining outer membrane integrity. {ECO:0000256|HAMAP-
CC Rule:MF_02202}.
CC -!- SUBUNIT: The Tol-Pal system is composed of five core proteins: the
CC inner membrane proteins TolA, TolQ and TolR, the periplasmic protein
CC TolB and the outer membrane protein Pal. They form a network linking
CC the inner and outer membranes and the peptidoglycan layer.
CC {ECO:0000256|HAMAP-Rule:MF_02202}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_02202}; Multi-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_02202}. Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-pass
CC membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the ExbB/TolQ family.
CC {ECO:0000256|ARBA:ARBA00010442, ECO:0000256|HAMAP-Rule:MF_02202}.
