CC   -!- FUNCTION: Participates in initiation and elongation during chromosome
CC       replication; it exhibits DNA-dependent ATPase activity and contains
CC       distinct active sites for ATP binding, DNA binding, and interaction
CC       with DnaC protein, primase, and other prepriming proteins.
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC   -!- SIMILARITY: Belongs to the helicase family. DnaB subfamily.
CC       {ECO:0000305}.
