ATP-dependent DNA helicase Hel308

UniProtKB accession:  O73946

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 homologous linear dsDNA.
