CC -!- FUNCTION: Bidirectionally degrades single-stranded DNA into large acid-
CC insoluble oligonucleotides, which are then degraded further into small
CC acid-soluble oligonucleotides. {ECO:0000255|HAMAP-Rule:MF_00337}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Exonucleolytic cleavage in either 5'- to 3'- or 3'- to 5'-
CC direction to yield nucleoside 5'-phosphates.; EC=3.1.11.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00337};
CC -!- SUBUNIT: Heterooligomer composed of large and small subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00337}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00337}.
CC -!- SIMILARITY: Belongs to the XseB family. {ECO:0000255|HAMAP-
CC Rule:MF_00337}.
