CC   -!- FUNCTION: Binds single-stranded DNA at the primosome assembly site
CC       (PAS). {ECO:0000255|HAMAP-Rule:MF_00720}.
CC   -!- SUBUNIT: Component of the preprimosomal complex composed of PriA, PriB,
CC       PriC, DnaB and DnaT. 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}.
