THE STRUCTURE OF AN OLIGO(DA).OLIGO(DT) TRACT AND ITS BIOLOGICAL IMPLICATIONS
Overview
Poly(dA).poly(dT) has unusual properties in that it cannot associate into nucleosomes and short, phased runs of it cause DNA bending. The crystal structure of a B-type DNA dodecamer containing a homopolymeric run of six A.T base pairs shows that this region possesses special structural features, including a system of bifurcated hydrogen bonds, which explains some of the properties of this simple homopolymer.
About this Structure
1D98 is a Protein complex structure of sequences from [1]. Full crystallographic information is available from OCA.
