CC -!- FUNCTION: Involved in the restart of stalled replication forks.
CC Recognizes and binds the arrested nascent DNA chain at stalled
CC replication forks. It can open the DNA duplex, via its helicase
CC activity, and promote assembly of the primosome and loading of the
CC major replicative helicase DnaB onto DNA. {ECO:0000255|HAMAP-
CC Rule:MF_00983}.
CC -!- SUBUNIT: Component of the primosome. {ECO:0000255|HAMAP-Rule:MF_00983}.
CC -!- SIMILARITY: Belongs to the helicase family. PriA subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00983}.
