Evidence for a Role of DNA Helicase II in DNA Replication

1981
Studies using antibodies raised against DNA helicase II of E.coli and applied to subcellular E.coli DNA replicating systems suggest that DNA helicase II participates in the unwinding of DNA molecules, which initiate replication as closed circles. A similar role for the rep protein has been implicated in the rolling circle model of replication of the ...

Biochemical Assays for the Characterization of DNA Helicases

2008
Helicases are ubiquitous enzymes that disrupt complementary strands of duplex nucleic acid in a reaction dependent on nucleoside-5'-triphosphate hydrolysis. Helicases are implicated in the metabolism of DNA structures that are generated during replication, recombination, and DNA repair. Furthermore, an increasing number of helicases have been linked to

DNA helicases in recombination

2007
The 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.
