[[http://www.uniprot.org/uniprot/DNAA_ECOLI DNAA_ECOLI]] Plays a key role in the initiation and regulation of chromosomal replication. Binds in an ATP-dependent fashion to the origin of replication (oriC) to initiate formation of the DNA replication initiation complex exactly once per cell cycle. Binds the DnaA box (consensus sequence 5'-TTATC[CA]A[CA]A-3'); subsequent binding of DNA polymerase III subunits leads to replisome formation. The DnaA-ATP form converts to DnaA-ADP; once converted to ADP the protein cannot initiate replication, ensuring only 1 round of replication per cell cycle. DnaA can inhibit its own gene expression as well as that of other genes such as dam, rpoH, ftsA and mioC.<ref>PMID:9242693</ref> <ref>PMID:16077105</ref> <ref>PMID:17699754</ref>  Also required for replication of plasmid DNA; binds 4 dnaA boxes in the minimal plasmid RK2 replication origin (oriV).<ref>PMID:9242693</ref> <ref>PMID:16077105</ref> <ref>PMID:17699754</ref>
