CC   -!- FUNCTION: Plays an important role in the initiation and regulation of
CC       chromosomal replication. Binds to the origin of replication; it binds
CC       specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'-
CC       TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DnaA family. {ECO:0000305}.
