Enzyme Information

3.6.4.12
DNA helicase.
based on mapping to UniProt Q5KU75
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).
