Scientific Background :  Single-stranded DNA binding protein (SSB) in E. coli is involved in DNA replication, repair, and recombination (1). SSB enhances helix destabilization by DNA helicases thus preventing reannealing of single-stranded DNA and nuclease digestion during DNA replication (1). E. coli SSB is required for methyl-directed mismatch repair, induction of the SOS response, and recombinational repair (1).  SSB interacts with DNA helicase RecQ of the RecF-recombination pathway and stimulates helicase activity (2). SSB also stabilizes replication origins, primosome assembly, plays a role in primosome assembly, enhances replication fidelity and polymerase processivity, and promotes polymerase binding to template DNA (1,2).
