    Type II restriction endonucleases recognize DNA sequences that vary between four to eight base pairs, and require only Mg2+ as a cofactor to catalyze the hydrolysis of DNA. Their protein sequences display a surprising lack of similarity, and no recurring structural motif analogous to the helix-turn-helix or the zinc finger of transcription factors, has yet been discovered.
