N2 - In the cell culture experiments, the AEDL peptide proved to be an efficient agent stimulating the cell renewal processes and the enhancement of the functional activity of bronchial epithelial cells. A presumed target of the peptide action is a DNA molecule. The work studies the peptide binding with high-molecular DNA in solutions with different ionic strengths. The spectral (UV spectophotometery and circular dichroism) and hydrodynamic (viscosimetry) methods show that, under the experimental conditions, the AEDL peptide forms a complex with DNA and that nitrogen bases are involved in the binding. The character of spectral changes in DNA suggests a possible interaction of the AEDL peptide with DNA in the major furrow at the guanine N7 site without a visible distortion of the double helix structure.
