CC -!- FUNCTION: May play a role in DNA repair. It seems to be involved in an
CC RecBC-independent recombinational process of DNA repair. It may act
CC with RecF and RecO. {ECO:0000255|HAMAP-Rule:MF_00017}.
CC -!- SIMILARITY: Belongs to the RecR family. {ECO:0000255|HAMAP-
CC Rule:MF_00017}.
CC -!- CAUTION: The sequence was elongated in the N-terminal section, to
CC maximize the similarity with other orthologs. We have not found a valid
CC start site, therefore we used an GTT. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB76676.1; Type=Erroneous initiation; Evidence={ECO:0000305};
