in the previous studies with endonucleases specific for single-stranded dna , we have indicated that the nonhistone chromosomal protein hmg ( 1 + 2 ) prepared from pig thymus has an activity to unwind dna partially at low protein-to-dna weight ratios ( yoshida , m. & shimura , k. ( 1984 ) j. biochem . 95 , 117-124 ) .
