FUNCTION:Required for efficient DNA repair; it catalyzes the unwinding of double-stranded DNA and the cleavage of single-stranded DNA and it stimulates local genetic recombination. All of these activities require concomitant hydrolysis of ATP.
CATALYTIC ACTIVITY:Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides.
SUBUNIT:Consist of three subunits; recB, recC and recD.
SIMILARITY:Belongs to the helicase family. UvrD subfamily.
