Dielectric study of the interaction between DNA and an oligopeptide (lysine-tyrosine-lysine).

M A Rix-Montel, H Grassi, D Vasilescu.   

Abstract

Interaction between Na-DNA and the oligopeptide lysine-tyrosine-lysine (LTL) is studied by a dielectric method. The comparison between conductivities (at the frequence of 5MHz) of LTL alone and of the complex LTL-DNA allows us to show up an electrostatic interaction between LTL and phosphates sites of DNA. During the formation of the complex LTL-DNA, a certain fraction of Na+ counter-ions is ejected from the phosphates sites.
