CRYSTAL STRUCTURE AND SEQUENCE-DEPENDENT CONFORMATION OF THE A.G MIS-PAIRED OLIGONUCLEOTIDE D(CGCAAGCTGGCG)
Overview
The crystal structure of the dodecanucleotide d(CGCAAGCTGGCG) has been determined to a resolution of 2.5 A and refined to an R factor of 19.3% for 1710 reflections. The sequence crystallizes as a B-type double helix, with two G(anti).A(syn) base pairs. These are stabilized by three-center hydrogen bonds to pyrimidines that induce perturbations in base-pair geometry. The central AGCT region of the helix has a wide (greater than 6 A) minor groove.
