CC -!- FUNCTION: Endonuclease that is involved in the suppression of
CC homologous recombination and may therefore have a key role in the
CC control of bacterial genetic diversity. {ECO:0000255|HAMAP-
CC Rule:MF_00092}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00092}.
CC -!- SIMILARITY: Belongs to the DNA mismatch repair MutS family. MutS2
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00092}.
