PriB RT facilitates complex formation between PriA and DnaT."; RL J. Biol. Chem. 271:15656-15661(1996). 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 priB CC and one hexamer of dnaB. Upon transient interaction with dnaG it CC forms the primosome. CC -!- SIMILARITY: Belongs to the priB family. CC -!- SIMILARITY: Contains 1 SSB domain.
