Minor-groove binders are inhibitors of the catalytic activity of DNA gyrases.
Non-intercalating DNA minor-groove binders may effectively inhibit the supercoiling activity of gyrases by influencing the enzyme recognition and cleavage site on DNA. For gyrase from Streptomyces noursei a wide range of inhibitory potency for different classes of ligands is observed. This can be explained by a number of structural and binding factors of the ligands competing with the gyrase on the target site of DNA, the mechanism of which is different from the classical gyrase inhibitors.
