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}.
