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}.
