Enzyme Information
| 3.1.21.3 |
Type I site-specific deoxyribonuclease.
based on mapping to UniProt P10486
Endonucleolytic cleavage of DNA to give random double-stranded fragments with terminal 5'-phosphates, ATP is simultaneously hydrolyzed.
-!- Large group of enzymes that 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. -!- Multifunctional proteins which also catalyze the reactions of EC 2.1.1.72 and EC 2.1.1.73, with similar site specificity. -!- Formerly EC 3.1.24.1 and EC 3.1.24.2. -!- See the REBASE database for a complete list of these enzymes: http://rebase.neb.com/rebase/
