Protein attributes

Sequence length	467 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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 By similarity. HAMAP MF_00377
Subcellular location	Cytoplasm By similarity HAMAP MF_00377.
Sequence similarities	Belongs to the DnaA family.
