CC   -!- FUNCTION: Site-specific tyrosine recombinase, which acts by catalyzing
CC       the cutting and rejoining of the recombining DNA molecules. The XerC-
CC       XerD complex is essential to convert dimers of the bacterial chromosome
CC       into monomers to permit their segregation at cell division. It also
CC       contributes to the segregational stability of plasmids (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Forms a cyclic heterotetrameric complex composed of two
CC       molecules of XerC and two molecules of XerD. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- INDUCTION: It is induced 4 hours after macrophage infection.
CC       {ECO:0000269|PubMed:11705955}.
CC   -!- SIMILARITY: Belongs to the 'phage' integrase family. XerD subfamily.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAJ11988.1; Type=Erroneous initiation; Evidence={ECO:0000305};
