dnaA | Chromosomal replication initiator protein DnaA, DNA-binding transcriptional dual regulator; 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 onl [...] (467 aa) | ||||
dnaB | Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity and contains distinct active sites for ATP binding, DNA binding, and interaction with DnaC protein, primase, and other prepriming proteins. (471 aa) |
