CC   -!- FUNCTION: Effects nucleoid occlusion by binding relatively
CC       nonspecifically to DNA and preventing the assembly of the division
CC       machinery in the vicinity of the nucleoid, especially under conditions
CC       that disturb the cell cycle. It helps to coordinate cell division and
CC       chromosome segregation by preventing the formation of the Z ring
CC       through the nucleoid, which would cause chromosome breakage.
CC       {ECO:0000255|HAMAP-Rule:MF_02015}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, nucleoid {ECO:0000255|HAMAP-
CC       Rule:MF_02015}.
CC   -!- SIMILARITY: Belongs to the ParB family. {ECO:0000255|HAMAP-
CC       Rule:MF_02015}.
