'''Single-stranded DNA-binding protein''' (SSB) binds to single-stranded regions of DNA (ssDNA) to protect it from annealing, prevention of secondary structure formation and digestion. SSB binds to DNA in a sequence-independent manner. The binding of SSB enables processes like replication, DNA repair and recombination to occur. SSB can form complexes with specific genome maintenance proteins helping their activities<ref>PMID:22976174</ref>.<br /> | '''Single-stranded DNA-binding protein''' (SSB) binds to single-stranded regions of DNA (ssDNA) to protect it from annealing, prevention of secondary structure formation and digestion.
