CC   -!- FUNCTION: Involved in chromosome condensation, segregation and cell
CC       cycle progression. May participate in facilitating chromosome
CC       segregation by condensation DNA from both sides of a centrally located
CC       replisome during cell division. Not required for mini-F plasmid
CC       partitioning. Probably acts via its interaction with MukB and MukE.
CC       Overexpression results in anucleate cells. It has a calcium binding
CC       activity. {ECO:0000255|HAMAP-Rule:MF_01803}.
CC   -!- SUBUNIT: Interacts, and probably forms a ternary complex, with MukE and
CC       MukB via its C-terminal region. The complex formation is stimulated by
CC       calcium or magnesium. It is required for an interaction between MukE
CC       and MukB. {ECO:0000255|HAMAP-Rule:MF_01803}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, nucleoid {ECO:0000255|HAMAP-
CC       Rule:MF_01803}. Note=Restricted to the nucleoid region.
CC       {ECO:0000255|HAMAP-Rule:MF_01803}.
CC   -!- SIMILARITY: Belongs to the MukF family. {ECO:0000255|HAMAP-
CC       Rule:MF_01803}.
