  • PubMed Abstract: 
  • 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 ...

    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.
