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_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:0000256|HAMAP-Rule:MF_00671}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000256|ARBA:ARBA00004418,
CC ECO:0000256|HAMAP-Rule:MF_00671}.
CC -!- SIMILARITY: Belongs to the TolB family. {ECO:0000256|ARBA:ARBA00009820,
CC ECO:0000256|HAMAP-Rule:MF_00671}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OSM01750.1}.
