Background: Multiple DnaA molecules form highly ordered complexes on the origin DNA to initiate chromosomal replication. Results: Novel structural motifs of DnaA are specifically required for the formation of the DNA unwinding-specific DnaA subcomplex. Conclusion: Distinct inter-DnaA interactions are required for the unwinding-specific subcomplex. Significance: Differentiation of the unwinding-specific subcomplex and a key mechanism underlying it are revealed.
