FunFam 7565: Restriction endonuclease S subunit

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Type I site-specific deoxyribonuclease. [EC: 3.1.21.3]
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.
