Bacterial system in which the Cre protein mediates DNA recombination between specific DNA sequences known as lox-P sites.
Note: This system is used in mammalian cells to delete (or invert) a stretch of DNA by flanking it with lox-P sites and then exposing the cell to Cre protein at some predetermined time.
