DnaA promotes the unwinding of the DNA helix. The cellular concentration of DnaA determines the initiation of DNA replication. Active DnaA is bound to ATP. DnaA binds to DNA at a specific 9 base pair DnaA box in oriC (origin of replication sequence). Protein-DNA interface (1j1v). For more details see Molecular Playground/DNA replication initiator DnaA.
