== Function ==
[https://www.uniprot.org/uniprot/HELS_PYRFU HELS_PYRFU] DNA-dependent ATPase and 3'-5' DNA helicase that may be involved in repair of stalled replication forks. Unwinds the lagging strand from forked DNA structures in a 3'-5' direction. PCNA, the DNA polymerase sliding clamp subunit, stimulates the helicase activity, and may alter substrate specificity. Unwinds branched DNA (Holliday junctions) in an ATP-dependent fashion; ss- and dsDNA stimulate ATPase to the greatest extent, although it preferentially binds DNA with a single-stranded region. Processes a RecA-mediated recombination intermediate between gapped circular and homologus linear dsDNA.<ref>PMID:15677450</ref> <ref>PMID:16436047</ref>
