Sequence-specific binding of [N-MeCys3,N-MeCys7]TANDEM to TpA.

The sequence selective binding of [N-MeCys3,N-MeCys7]TANDEM to DNA has been studied by footprinting experiments on DNA fragments containing the self-complementary sequences CGCGATATCGCG, CGCGTATACGCG, CGCGTTAACGCG and CGCGAATTCGCG. DNAase I and micrococcal nuclease reveal drug-induced footprints with the central sequences ATAT, TATA and TTAA, but not AATT… CONTINUE READING
