CC -!- FUNCTION: Participates in initiation and elongation during chromosome
CC replication; it exhibits DNA-dependent ATPase activity. {ECO:0000250}.
CC -!- FUNCTION: The intein is an endonuclease. {ECO:0000305}.
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 -!- PTM: This protein undergoes a protein self splicing that involves a
CC post-translational excision of the intervening region (intein) followed
CC by peptide ligation.
CC -!- SIMILARITY: Belongs to the helicase family. DnaB subfamily.
CC {ECO:0000305}.
