CC   -!- FUNCTION: Critical role in recombination and DNA repair. Helps process
CC       Holliday junction intermediates to mature products by catalyzing branch
CC       migration. Has a DNA unwinding activity characteristic of a DNA
CC       helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y-
CC       DNA) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.12;
CC   -!- SIMILARITY: Belongs to the helicase family. RecG subfamily.
CC       {ECO:0000305}.
