Molecular Characterization of Nuclear DNA Helicase II (RNA Helicase A)
2009Nuclear DNA helicase II (NDH II) was first isolated from calf thymus using a DNA-unwinding assay. Subsequently it has been shown to be a homologue of human RNA helicase A (RHA) and the maleless protein (MLE) from Drosophila. Accordingly, the protein possesses both DNA and RNA unwinding activities.

Helicases at the Replication Fork
2012Helicases are fundamental components of all replication complexes since unwinding of the double-stranded template to generate single-stranded DNA is essential to direct DNA synthesis by polymerases. However, helicases are also required in many other steps of DNA replication. Replicative helicases not only unwind the template DNA but also play key roles

DNA helicases in recombination
2007The different pathways of homologous recombination involve the recognition and pairing of homologous DNA sequences promoted by proteins that catalyze strand exchange. Other steps in recombination involve double stranded DNA unwinding for branch migration activities, and in some cases the reannealing of single DNA strands.
