CC   -!- FUNCTION: Essential cell division protein. May link together the
CC       upstream cell division proteins, which are predominantly cytoplasmic,
CC       with the downstream cell division proteins, which are predominantly
CC       periplasmic. {ECO:0000255|HAMAP-Rule:MF_00599}.
CC   -!- SUBUNIT: Part of a complex composed of FtsB, FtsL and FtsQ.
CC       {ECO:0000255|HAMAP-Rule:MF_00599}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00599}; Single-pass type II membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00599}. Note=Localizes to the division
CC       septum. {ECO:0000255|HAMAP-Rule:MF_00599}.
CC   -!- SIMILARITY: Belongs to the FtsB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00599}.
