RT scale genomic rearrangement in invasive strains and new insights into phage
RT evolution.";
RL Genome Res. 13:1042-1055(2003).
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}.
