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:0000255|HAMAP-
CC       Rule:MF_00671}.
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:0000255|HAMAP-Rule:MF_00671}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_00671}.
CC   -!- SIMILARITY: Belongs to the TolB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00671}.
