"Involved in the restart of stalled replication forks, which reloads the replicative helicase on sites other than the origin of replication; the PriA-PriB pathway is the major replication restart pathway. During primosome assembly it facilitates complex formation between PriA and DnaT on DNA; stabilizes PriA on DNA. Stimulates the DNA unwinding activity of PriA helicase."xsd:string
