WebA key enzyme is RecA, which catalyzes the strand invasion process. RecA coats single-stranded DNA and facilitates its pairing with a double-stranded DNA molecule containing the same sequence, which produces a loop structure. Another protein, known as RecBC, is important for the recombination process.
