CC   -!- FUNCTION: Binds single-stranded DNA at the primosome assembly site
CC       (PAS). During primosome assembly it facilitates the complex formation
CC       between PriA and DnaT. {ECO:0000255|HAMAP-Rule:MF_00720}.
CC   -!- SUBUNIT: Component of the preprimosomal complex composed of one monomer
CC       of PriC and DnaT, two monomers of PriA, two dimers of PriB and one
CC       hexamer of DnaB. Upon transient interaction with DnaG it forms the
CC       primosome. {ECO:0000255|HAMAP-Rule:MF_00720}.
CC   -!- SIMILARITY: Belongs to the PriB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00720}.
