"Monomer. Hexamer. Interacts with the DnaB-like replicative helicase; this interaction forms the active primosome complex, which is composed of 6 helicase and 1 primase subunits and expresses full helicase and primase activities. Interacts (via C-terminus) with the single-stranded DNA-binding protein. Part of the replicase complex that includes the DNA polymerase, the polymerase clamp, the clamp loader complex, the single-stranded DNA binding protein, the primase, the DnaB-like replicative helicase and the helicase assembly factor."xsd:string
