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 -!- DEVELOPMENTAL STAGE: More than twofold more abundant in the small cell
CC variant (SCV) stage than in the large cell variant (LCV) stage (at
CC protein level). LCVs are more metabolically active than SCVs.
CC {ECO:0000269|PubMed:17088354}.
CC -!- SIMILARITY: Belongs to the TolB family. {ECO:0000255|HAMAP-
CC Rule:MF_00671}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAO89656.2; Type=Erroneous initiation; Evidence={ECO:0000305};
