CC   -!- FUNCTION: Site-specific tyrosine recombinase, which acts by catalyzing
CC       the cutting and rejoining of the recombining DNA molecules. Essential
CC       to convert dimers of the bacterial chromosome into monomers to permit
CC       their segregation at cell division. {ECO:0000255|HAMAP-Rule:MF_01816}.
CC   -!- ACTIVITY REGULATION: FtsK is required for recombination.
CC       {ECO:0000255|HAMAP-Rule:MF_01816}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01816}.
CC   -!- SIMILARITY: Belongs to the 'phage' integrase family. XerS subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01816}.
CC   -!- SEQUENCE CAUTION:
