abstract：:Replication of the bacterial chromosome is initiated by the binding of the DnaA protein to a unique DNA region, called oriC. Many regulatory factors in numerous species act by controlling the ability of DnaA to bind and unwind DNA, but the Helicobacter pylori genome does not contain homologues to any of these factors....
