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}.
