FunFam 60646: ATP-dependent DNA helicase RuvA

There are 2 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
DNA helicase. [EC: 3.6.4.12]
ATP + H(2)O = ADP + phosphate.
  • DNA helicases utilize the energy from ATP hydrolysis to unwind double-stranded DNA.
  • Some of them unwind duplex DNA with a 3' to 5' polarity (1,3,5,8), other show 5' to 3' polarity (10,11,12,13) or unwind DNA in both directions (14,15).
  • Some helicases unwind DNA as well as RNA (4,9).
  • May be identical with EC 3.6.4.13 (RNA helicase).

Crossover junction endodeoxyribonuclease. [EC: 3.1.22.4]
Endonucleolytic cleavage at a junction such as a reciprocal single- stranded crossover between two homologous DNA duplexes (Holliday junction).
  • The enzyme from Saccharomyces cerevisiae has no endonuclease or exonuclease activity on single-stranded or double-stranded DNA molecules that do not contain Holliday junctions.
