General annotation (Comments)

Function

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 By similarity.

Catalytic activity

ATP + H2O = ADP + phosphate.

Sequence similarities

Belongs to the helicase family. DnaB subfamily.

Contains 1 SF4 helicase domain.
