Annotation
do not confuse entry term DNA UNWINDING PROTEINS with DNA UNTWISTING PROTEINS
Scope Note
Proteins that catalyze the unwinding of duplex DNA during replication by binding cooperatively to single-stranded regions of DNA or to short regions of duplex DNA that are undergoing transient opening. In addition, DNA helicases are DNA-dependent ATPases that harness the free energy of ATP hydrolysis to translocate DNA strands.
Entry Term(s)
ATP-Dependent DNA Helicase
ATP-Dependent DNA Helicases
DNA Helicase
DNA Helicase A
DNA Helicase E
DNA Helicase II
DNA Helicase III
DNA Unwinding Protein
DNA Unwinding Proteins
