CC -!- FUNCTION: Negative regulator of replication initiation, which
CC contributes to regulation of DNA replication and ensures that
CC replication initiation occurs exactly once per chromosome per cell
CC cycle. Binds to pairs of hemimethylated GATC sequences in the oriC
CC region, thus preventing assembly of replication proteins and re-
CC initiation at newly replicated origins. Repression is relieved when the
CC region becomes fully methylated. {ECO:0000255|HAMAP-Rule:MF_00908}.
CC -!- SUBUNIT: Homodimer. Polymerizes to form helical filaments.
CC {ECO:0000255|HAMAP-Rule:MF_00908}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00908}.
CC -!- SIMILARITY: Belongs to the SeqA family. {ECO:0000255|HAMAP-
CC Rule:MF_00908}.
