ATP + H2O ATP-dependent DNA unwinding enzyme. HDH VI unwinds exclusively DNA duplexes with an annealed portion smaller than32 bp and prefers a replication fork-like structure of the substrate. It cannot unwind blunt-end duplexes and is inactive also on DNA-RNA or RNA-RNA hybrids. HDH VI unwinds DNA unidirectionally by moving in the 3' to 5' direction along the bound strand. ATP and dATP are equally good substrates Homo sapiens ADP + phosphate
