CC   -!- FUNCTION: This pseudogene is the C-terminal fragment of low activity
CC       DNA endonuclease RpnD which probably yields 3'-hydroxyl ends (By
CC       similarity). The intact protein can be seen in this entry (AC B7NGZ6).
CC       Expression of the repaired protein increases the frequency of recA-
CC       independent recombination, but also decreases viability probably via
CC       DNA damage; in a RecA strain expression has no effect on viability but
CC       does induce the SOS repair response (PubMed:26162088, PubMed:26618540).
CC       May play a role in horizontal gene transfer (PubMed:26162088,
CC       PubMed:26618540, PubMed:28096446). {ECO:0000250|UniProtKB:P31667,

CC       ECO:0000269|PubMed:28096446}.
CC   -!- SIMILARITY: Belongs to the Rpn/YhgA-like nuclease family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Could be the product of a pseudogene. Experiments were
CC       performed with a repaired version of the protein (AC B7NGZ6)
CC       (PubMed:26162088). {ECO:0000269|PubMed:26162088, ECO:0000305}.
