    Pyrococcus furiosus Hjm (PfuHjm) is a structure-specific DNA helicase that was originally identified by in vitro screening for Holliday junction migration activity. It belongs to helicase superfamily 2, and shares homology with the human DNA polymerase Theta (PolTheta), HEL308, and Drosophila Mus308 proteins, which are involved in DNA repair. Previous biochemical and genetic analyses revealed that PfuHjm preferentially binds to fork-related Y-structured DNAs and unwinds their double-stranded regions, suggesting that this helicase is a functional counterpart of the bacterial RecQ helicase, which is essential for genome maintenance. Elucidation of the DNA unwinding and translocation mechanisms by PfuHjm will require its three-dimensional structure at atomic resolution.
