Comments [?]

Function Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA.
Subunit Component of the primosome.
Similarity Belongs to the helicase family. PriA subfamily.
