RL   Submitted (JUN-2008) to the EMBL/GenBank/DDBJ databases.
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}.
