Comments [?]

Function Bidirectionally degrades single-stranded DNA into large acid-insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides.
Catalytic activity Reaction=Exonucleolytic cleavage in either 5'- to 3'- or 3'- to 5'-direction to yield nucleoside 5'-phosphates.; EC=3.1.11.6;
Subunit Heterooligomer composed of large and small subunits.
Subcellular location Cytoplasm.
Similarity Belongs to the XseB family.
