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       extracellular. {ECO:0000255|HAMAP-Rule:MF_00599}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Single-pass type II membrane
CC       protein. Note=Localizes to the division septum. {ECO:0000255|HAMAP-
CC       Rule:MF_00599}.
CC   -!- SIMILARITY: Belongs to the FtsB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00599}.
