  • Title: U-pin polyamide motif for recognition of the DNA minor groove.
    Author: Heckel A, Dervan PB.
    Journal: Chemistry; 2003 Jul 21; 9(14):3353-66. PubMed ID: 12866079.
    Abstract:
    DNA-binding hairpin pyrrole-imidazole polyamides with gamma-aminobutyric acid as a turn-forming residue tolerate A.T or T.A base pairs under the turn. U-pins-polyamides with a different turn-have been synthesized and their DNA binding properties were studied. The two turn-forming residues are connected via the ring nitrogens using variable length aliphatic linkers ((CH(2))(n), n=3-6). Through optimization of the linker length and the substituents at the 2-position of the pyrrole residue on the U-turn, polyamides with G.C/C.G tolerant turns could be found, which bind to DNA in a predictable manner.
