Catalysis of the reaction: ATP + H2O = ADP + phosphate to drive the unwinding of a DNA or RNA helix. Catalysis of the reaction: ATP + H2O = ADP + phosphate; drives the unwinding of the DNA helix in the direction 3' to 5'. Catalysis of the reaction: ATP + H2O = ADP + phosphate; drives the unwinding of the DNA helix in the direction 5' to 3'. Catalysis of the reaction: ATP + H2O = ADP + phosphate, driving the unwinding of the DNA helix. Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive some other reaction, for example ion transport across a membrane. Catalysis of the reaction: ATP + H2O = ADP + phosphate, in the presence of single-stranded DNA; drives the unwinding of a DNA helix. Catalysis of the reaction: NTP + H2O = NDP + phosphate to drive the unwinding of a DNA or RNA helix. Catalysis of the reaction: NTP + H2O = NDP + phosphate to drive the unwinding of a DNA helix. Catalysis of the reaction: ATP + H2O = ADP + phosphate in the presence of single- or double-stranded DNA; drives another reaction. Catalysis of the reaction: purine NTP + H2O = purine NDP + phosphate to drive the unwinding of a DNA or RNA helix.
