CC   -!- FUNCTION: Required for nucleoid occlusion (NO) phenomenon, which
CC       prevents Z-ring formation and cell division over the nucleoid. Acts as
CC       a DNA-associated cell division inhibitor that binds simultaneously
CC       chromosomal DNA and FtsZ, and disrupts the assembly of FtsZ polymers.
CC       SlmA-DNA-binding sequences (SBS) are dispersed on non-Ter regions of
CC       the chromosome, preventing FtsZ polymerization at these regions.
CC       {ECO:0000255|HAMAP-Rule:MF_01839}.
CC   -!- SUBUNIT: Homodimer. Interacts with FtsZ. {ECO:0000255|HAMAP-
CC       Rule:MF_01839}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, nucleoid {ECO:0000255|HAMAP-
CC       Rule:MF_01839}.
CC   -!- SIMILARITY: Belongs to the nucleoid occlusion factor SlmA family.
CC       {ECO:0000255|HAMAP-Rule:MF_01839}.
