CC   -!- FUNCTION: Site-specific tyrosine recombinase, which acts by catalyzing
CC       the cutting and rejoining of the recombining DNA molecules. Binds
CC       cooperatively to specific DNA consensus sequences that are separated
CC       from XerD binding sites by a short central region, forming the
CC       heterotetrameric XerC-XerD complex that recombines DNA substrates. The
CC       complex is essential to convert dimers of the bacterial chromosome into
CC       monomers to permit their segregation at cell division. It also
CC       contributes to the segregational stability of plasmids. In the complex
CC       XerC specifically exchanges the top DNA strands. {ECO:0000255|HAMAP-
CC       Rule:MF_01808}.
CC   -!- ACTIVITY REGULATION: FtsK may regulate the catalytic switch between
CC       XerC and XerD in the heterotetrameric complex during the two steps of
CC       the recombination process. {ECO:0000255|HAMAP-Rule:MF_01808}.
CC   -!- SUBUNIT: Forms a cyclic heterotetrameric complex composed of two
CC       molecules of XerC and two molecules of XerD, in which XerC interacts
CC       with XerD via its C-terminal region, XerD interacts with XerC via its
CC       C-terminal region and so on. {ECO:0000255|HAMAP-Rule:MF_01808}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01808}.
CC   -!- SIMILARITY: Belongs to the 'phage' integrase family. XerC subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01808}.
