Abstract:
:Three DNA restriction fragments designated tyrT, 102-mer and 70-mer, have been used as substrates for footprinting studies using DNase I in the presence of the structurally similar antibiotics chartreusin and elsamicin A. The sequence-selective binding sites of the antibiotics can be mapped in regions which are rich in guanine + cytosine. Chartreusin and elsamicin appear to recognize and bind preferentially to sequences containing a CpG step. Regions containing a TpG step also seem to be a good binding site. The binding of elsamicin to these sites appears to be more concentration-dependent. A comparative analysis is performed of the sizes and locations of the different binding sites, aimed to infer whether the different biological effects of chartreusin and elsamicin A can be correlated to differences in their sequence-selective binding to DNA.
