General annotation (Comments)

Function

Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'-TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids. DnaA can inhibit its own gene expression as well as that of other genes such as dam, rpoH, ftsA and mioC. Ref.9

Subunit structure

Some 20 DnaA protein molecules bind their sites in oriC. Forms a large complex with ATP-DnaA, ADP-Hda and the DNA-loaded clamp. Interacts with DiaA; this stimulates the association of DnaA with the origin of replication. Ref.9 Ref.10

Subcellular location

Cytoplasm HAMAP-Rule MF_00377.

Sequence similarities

Belongs to the DnaA family.
