The effects of substitution of O6-methylguanine on the structure and stability of a human telomere quadruplex was studied by circular dichroism; thermal denaturation; analytical ultracentrifugation; and molecular dynamics simulations. The results show that; while quadruplex structures can form containing the modified base; they are much less stable than the normal unmodified structure. The extent of destabilization is critically dependent on the exact position of the modified base within the quadruplex structure. Copyright © 2008 American Chemical Society;
