DnaA is in the active form only when bound to ATP.

#Unit 3. Fundamental Processes

Dna A has intrinsic ATPase activity that hydrolyzes ATP to ADP and thus inactivates itself when the initiation stage ends.

#Unit 3. Fundamental Processes

This ATPase activity of Dna A is stimulated by membrane phospholipids and single-stranded DNA.

The origin of the replication region remains attached to the membrane for about one-third of the cell cycle as another part of the mechanism to prevent reinitiation.

#Unit 3. Fundamental Processes

The four 9-bp consensus sequences on the right side of oriC provide the initial binding sites for DnaA-ATP in an extended multimeric state promoted by the accessory protein DiaA, which stimulates cooperative binding of DnaA.
