FunFam 633675: ATP-dependent DNA helicase Hel308

There are 4 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).

DNA-directed DNA polymerase. [EC: 2.7.7.7]
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
  • Catalyzes DNA-template-directed extension of the 3'-end of a DNA strand by one nucleotide at a time.
  • Cannot initiate a chain de novo.
  • Requires a primer which may be DNA or RNA.
  • See also EC 2.7.7.49.

Ribulose-bisphosphate carboxylase. [EC: 4.1.1.39]
2 3-phospho-D-glycerate + 2 H(+) = D-ribulose 1,5-bisphosphate + CO(2) + H(2)O.
  • Will utilize O(2) instead of CO(2), forming 3-phospho-D-glycerate and 2-phosphoglycolate.

RNA helicase. [EC: 3.6.4.13]
ATP + H(2)O = ADP + phosphate.
  • RNA helicases utilize the energy from ATP hydrolysis to unwind RNA.
  • Some of them unwind RNA with a 3' to 5' polarity, other show 5' to 3' polarity.
  • Some helicases unwind DNA as well as RNA.
  • May be identical with EC 3.6.4.12 (DNA helicase).
