Single-stranded DNA-binding protein

UniProtKB accession:  Q9RY51

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism (By similarity). Essential for ionizing radiation resistance. Stimulates the 5'-3' DNA helicase activity of RecD-like helicase. Stimulates RecA protein-promoted DNA three-strand exchange reactions in vitro with both D.radiodurans and E.coli-derived RecA. Complements an ssb deletion in E.coli, but does not complement a ddrb disruption in D.radiodurans.
