Single strands induce recA protein to unwind duplex DNA for homologous pairing.

R P Cunningham, T Shibata, C DasGupta, C M Radding.   

Abstract

Single-stranded DNA, whether homologous or not, stimulates purified Escherichia coli recA protein to unwind duplex DNA. This helps to explain how recA promotes a search for homology in genetic recombination. As oligodeoxynucleotide also stimulate unwinding, a common mechanism may relate the function of recA protein in recombination to other functions (SOS) induced by oligonucleotides.
