A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 3.1.21.5

Accepted Name
Type III site-specific deoxyribonuclease.
Alternative Name(s)
Type III restriction enzyme.
Reaction catalysed
Endonucleolytic cleavage of DNA to give specific double-stranded fragments with terminal 5'-phosphates
Comment(s)
  • Has an absolute requirement for ATP, but does not hydrolyze it; S-adenosyl-L-methionine stimulates the reaction, but is not absolutely required.
  • Recognize specific short DNA sequences and cleave a short distance away from the recognition sequence.
  • Exist as complexes with enzymes of similar specificity listed under EC 2.1.1.72 or EC 2.1.1.73.
  • Formerly EC 3.1.24.3 and EC 3.1.24.4.
  • See the REBASE database for a complete list of these enzymes: http://rebase.neb.com/rebase/
