Аннотация: Interaction of DNA with the analogs of the antibiotic distamycin A having different numbers of pyrrolcarboxamide groups and labeled with dansyl was studied. The binding isoterms of the analogs to synthetic polydeoxyribonucleotides were obtained. Analysis of the experimental data leads to the following conclusions: (1) the free energy of binding of the analogs to poly(dA)«poly(dT) depends linearly on the number of amide groups in the molecule of the analog whereas attachment of each pyrrolcarboxamide group produces changes of 2 kcal/mole in the free energy; (2; attachment of a pyrrolcarboxamide unit to the GC pair results in the free energy change of 0.95 kcal/mole; (3) the binding of analogs to poly(dA)«poly(dT) is a cooperative process, presumbly, dependent on conformational changes Induced by the binding of analogs to DNA.
