Notes
DnaA-ATP is the active form; DnaA-ADP is inactive; switching betwee the two forms modulates initiation activity. Acidic phospholipids release bound ADP, reactivating DnaA by allowing ATP to rebind. Null mutations in seqA, yccV or rpoN suppress dna46(Ts). Increases in DnaA levels reduce Fis oriC primary binding thus allowing DnaA to bind, this may play a role in the dynamics of prereplication complexes. Collapsed replication forks (primarily within 10 map units of oriC) are a result of the level of initiation induced by elevated dnaA expression. Hda-ADP is the monomeric active form for promoting clamp-mediated DNA-ATP hydrolysis (Su'etsugu, 2008).[4]
