Reaction

Cofactor

Comments:

This is a large group of enzymes which, together with those now listed as EC 3.1.21.3 (type I site-specific deoxyribonuclease) and EC 3.1.21.5 (type III site-specific deoxyribonuclease), were previously listed separately in sub-subclasses 3.1.23 and 3.1.24. They require only Mg2+. They recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition site. A complete listing of all of these enzymes has been produced by R.J. Roberts and is available at http://rebase.neb.com/rebase/rebase.html.
