RT "Marinorhizobium profundi gen. nov., sp. nov., isolated from a deep-sea
RT sediment sample from the New Britain Trench and proposal of
RT Marinorhizobiaceae fam. nov. in the order Rhizobiales of the class
RT Alphaproteobacteria.";
RL Submitted (SEP-2018) 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:0000256|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:0000256|HAMAP-Rule:MF_00337};
CC -!- SUBUNIT: Heterooligomer composed of large and small subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00337}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00337}.
CC -!- SIMILARITY: Belongs to the XseB family. {ECO:0000256|ARBA:ARBA00009998,
CC ECO:0000256|HAMAP-Rule:MF_00337}.
