Abstract

α(1,4) glucopyranose chains (dextrins) are shown to interact with DNA via hydrophobic interactions from the minor groove side, while α(1,6) dextrans do not bind DNA. The observed specific α(1,4) linked sugar-DNA interactions may have importance in recognition of DNA by ene-diyne class of antibiotics via their saccharide units which have mostly α(1,4) linkages.
