Protein name

RecName: Full=Exodeoxyribonuclease 7 small subunit; EC=3.1.11.6; AltName: Full=Exodeoxyribonuclease VII small subunit; Short=Exonuclease VII small subunit;

Gene name

xseB

FUNCTION: Bidirectionally degrades single-stranded DNA into large acid-insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides (By similarity).

CATALYTIC ACTIVITY: Exonucleolytic cleavage in either 5'- to 3'- or 3'- to 5'-direction to yield nucleoside 5'-phosphates.

SUBUNIT: Heterooligomer composed of large and small subunits (By similarity).

SUBCELLULAR LOCATION: Cytoplasm (By similarity).

SIMILARITY: Belongs to the XseB family.
