  • Title: Restriction of single-stranded M13 DNA using synthetic oligonucleotides: the structural requirement of restriction enzymes.
    Author: Qi GR, Wong P, Cedergren R.
    Journal: Biochem Cell Biol; 1987 Jan; 65(1):50-5. PubMed ID: 3032219.
    Abstract:
    A targeted ss (single stranded) DNA cleavage technique is reported which involves the use of synthetic oligomers complementary to the ss M13 DNA polylinker. BamHI, SmaI, and KpnI restriction enzymes were tested with a partial duplex DNA formed from ss M13 DNA and a nested series of fragments derived from a synthetic 21-mer which were complementary to the polylinker region. These enzymes require up to two flanking nucleotides in addition to the hexameric recognition site for efficient cleavage. This technique could be useful for effecting unique cleavages of DNA with enzymes which generally give a large number of fragments and for strategies of ss DNA manipulation.
