===MOLECULAR STRUCTURE OF THE B-DNA DODECAMER D(CGCAAATTTGCG)2; AN EXAMINATION OF PROPELLER TWIST AND MINOR-GROOVE WATER STRUCTURE AT 2.2 ANGSTROMS RESOLUTION===

~~==Overview==~~

<!--

The ~~crystal structure of~~ the ~~dodecanucleotide duplex d(CGCAAATTTGCG)2 has been solved to 2.2 A resolution and refined~~ to ~~an R-factor of 18.1% with~~ the ~~inclusion of 71 water molecules~~. ~~The structure shows propeller twists of up to -20 degrees for the A~~.~~T base-pairs~~, ~~although there~~ is ~~probably only one (weak) three-centre hydrogen bond in~~ the ~~six base~~-~~pair AT narrow minor~~-groove region. An extensive ribbon of hydration has been located in this groove that has features distinctive from the classic "spine of hydration". Solvation around phosphate groups is described, with several instances of water molecules bridging between phosphates.

The line below this paragraph, {{ABSTRACT_PUBMED_1518049}}, adds the Publication Abstract to the page

(as it appears on PubMed at http://www.pubmed.gov), where 1518049 is the PubMed ID number.
