CC   -!- FUNCTION: Binds single-stranded DNA at the primosome assembly site
CC       (PAS). During primosome assembly it facilitates the complex
CC       formation between priA and dnaT.
CC   -!- SUBUNIT: Component of the preprimosomal complex composed of one
CC       monomer of priC and dnaT, two monomers of priA, two dimers of
CC       priB and one hexamer of dnaB. Upon transient interaction with
CC       dnaG it forms the primosome.
CC   -!- SIMILARITY: Belongs to the priB family.
CC   -!- SIMILARITY: Contains 1 SSB domain.
