Exodeoxyribonuclease 7 small subunit

UniProtKB accession:  P0A8G9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bidirectionally degrades single-stranded DNA into large acid-insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides. It can degrade 3' or 5' ss regions extending from the termini of duplex DNA molecules and displaced ss regions. It can also excise thymine dimers in vitro (PubMed:4602029, PubMed:4602030, PubMed:22718974) (Probable). Required for production of the mature 5'-end of retron Ec78 or Ec83 msDNA. When in excess of the large subunit, counteracts the large subunit's toxicity (PubMed:26626352).
