Interacting selectively with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose moiety [goid 166] [evidence IEA]; Interacting selective with DNA that contains a bubble. A bubble occurs when DNA contains a region of unpaired, single-stranded DNA flanked on both sides by regions of paired, double-stranded DNA [goid 405] [pmid 11433031] [evidence IDA]; Facilitates the base-pairing of complementary single-stranded DNA [goid 739] [pmid 17878217] [evidence IDA]; Interacting selectively with one of the p53 family of proteins [goid 2039] [pmid 11781842] [evidence IPI]; Interacting selectively with DNA (deoxyribonucleic acid) [goid 3677] [evidence IEA]; Interacting selectively with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator [goid 5524] [pmid 17878217] [evidence IDA]; Catalysis of the unwinding of the DNA helix of DNA containing four-way junctions, including Holliday junctions [goid 9378] [pmid 11433031] [evidence IDA]; Catalysis of the unwinding of the DNA helix of DNA containing four-way junctions, including Holliday junctions [goid 9378] [pmid 12818200] [evidence IDA]; Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3 [goid 16787] [evidence IEA]; Catalysis of the hydrolysis of any acid anhydride which contains phosphorus [goid 16818] [evidence IEA]; Catalysis of the reaction: ATP + H2O = ADP + phosphate. May or may not be coupled to another reaction [goid 16887] [pmid 17878217] [evidence IDA]; Catalysis of the reaction: ATP + H2O = ADP + phosphate; drives the unwinding of the DNA helix in the direction 3' to 5' [goid 43140] [evidence IEA]; Interacting selectively with G-quadruplex DNA structures, in which groups of four guanines adopt a flat, cyclic Hoogsteen hydrogen-bonding arrangement known as a guanine tetrad. The stacking of guanine tetrads results in G-quadruplex DNA structures. G-quadruplex DNA can form under physiological conditions from some G-rich sequences, such as those found in telomeres, immunoglobulin switch regions, gene promoters, fragile X repeats, and the dimerization domain in the human immunodeficiency virus (HIV) genome [goid 51880] [pmid 11433031] [evidence IDA]
