'''MOLECULAR STRUCTURE OF A LEFT-HANDED DOUBLE HELICAL DNA FRAGMENT AT ATOMIC RESOLUTION'''<br />

==Overview==

The DNA fragment d(CpGpCpGpCpG) crystallises as a left-handed double helical molecule with Watson-Crick base pairs and an antiparallel organisation of the sugar phosphate chains. The helix has two nucleotides in the asymmetric unit and contains twelve base pairs per turn. It differs significantly from right-handed B-DNA.

 

==About this Structure==

2DCG is a [http://en.wikipedia.org/wiki/Protein_complex Protein complex] structure of sequences from [http://en.wikipedia.org/wiki/ ] with <scene name='pdbligand=MG:'>MG</scene> and <scene name='pdbligand=SPM:'>SPM</scene> as [http://en.wikipedia.org/wiki/ligands ligands]. The following page contains interesting information on the relation of 2DCG with [[http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/pdb23_1.html DNA]].
