HIGH RESOLUTION NMR STRUCTURE OF THE STEREOREGULAR (ALL-RP)-PHOSPHOROTHIOATE-DNA/RNA HYBRID D (G*PS*C*PS*G*PS*T*PS*C*PS*A*PS*G*PS*G)R(CCUGACGC), MINIMIZED AVERAGE STRUCTURE
Overview
In this work, we present the first NMR solution structure of a DNA/RNA hybrid containing stereoregular Rp-phosphorothioate modifications of all DNA backbone linkages. The complex of the enzymatically synthesized phosphorothioate DNA octamer (all-Rp)-d(GCGTCAGG) and its complementary RNA r(CCUGACGC) was found to adopt an overall conformation within the A-form family. Most helical parameters and the sugar puckers of the DNA strand assume values intermediate between A- and B-form. The close structural similarity with the unmodified DNA/RNA hybrid of the same sequence may explain why both the natural and the sulfur-substituted complex can be recognized and digested by ribonuclease H.
