Protein namei

  • Recommended name:
    Primosomal replication protein N

Gene namei

  • Name:priB

Functioni

  • Stimulates the DNA unwinding activity of PriA helicase, which does not seem to require single-stranded DNA-binding by PriB. Activates DNA-dependent ATP hydrolysis catalyzed by PriA.
  • Binds single-stranded DNA at the primosome assembly site (PAS). During primosome assembly it facilitates the complex formation between PriA and DnaT.
  • Binds single-stranded DNA at the primosome assembly site (PAS).

Sequence similaritiesi

Subunit structurei

  • Homodimer. Component of the preprimosomal complex.
  • Component of the preprimosomal complex composed of one monomer of PriC and DnaT, two monomers of PriA, two dimers of PriB and one hexamer of DnaB. Upon transient interaction with DnaG it forms the primosome.
  • Component of the preprimosomal complex composed of PriA, PriB, PriC, DnaB and DnaT. Upon transient interaction with DnaG it forms the primosome.
