EC Number 3.1.21.3
CAS编号 37263-09-5
Comments This is a large group of enzymes which, together with those now listed as EC?3.1.21.4?(type II site-specific deoxyribonuclease) and EC?3.1.21.5?(type III site-specific deoxyribonuclease), were previously listed separately in sub-subclasses EC?3.1.23?and EC?3.1.24. They have an absolute requirement for ATP (or dATP) and?S-adenosyl-L-methionine. They recognize specific short DNA sequences and cleave at sites remote from the recognition sequence. They are multifunctional proteins that also catalyse the reactions of EC?2.1.1.72?[site-specific DNA-methyltransferase (adenine-specific)] and EC?2.1.1.73?[site-specific DNA-methyltransferase (cytosine-specific)], with similar site specificity. A complete listing of all of these enzymes has been produced by R.J. Roberts and is available at http://rebase.neb.com/rebase/.
Cofactor
History
Reactions Endonucleolytic cleavage of Dna to give random double-stranded fragments with terminal 5′-phosphates; Atp is simultaneously hydrolyzed.
