CC   -!- FUNCTION: Involved in DNA repair and RecF pathway recombination (By
CC       similarity). Plays no role in chromosomal or plasmid transformation but
CC       is required for resolution of chromosome dimers occurring as
CC       intermediates in the formation of merodiploids by transformation

CC       ECO:0000269|PubMed:25569614}.
CC   -!- DISRUPTION PHENOTYPE: Mutant is sensitive to the alkylating agent
CC       methyl methanesulfonate and the DNA cross-linking agent mitomycin C.
CC       {ECO:0000269|PubMed:25569614}.
CC   -!- SIMILARITY: Belongs to the RecO family. {ECO:0000255|HAMAP-
CC       Rule:MF_00201}.
