Primosomal replication protein PriB <p>PriB is a component of the preprimosomal complex. The preprimosomal complex is composed of one monomer of PriC and DnaT, two monomers of PriA, two dimers of PriB and one hexamer of DnaB. Upon transient interaction with DnaG it forms the primosome [<cite idref="PUB00054930"/>].</p><p>PriB binds single-stranded DNA at the primosome assembly site (PAS) [<cite idref="PUB00054931"/>, <cite idref="PUB00054932"/>, <cite idref="PUB00054933"/>]. Assembly of the primosome is initiated by interactions of PriA and PriB with ssDNA and the PAS [<cite idref="PUB00054933"/>].</p>
