Sugar and Phosphate Constituents

The following tables contain the complete references for the structures used in a statistical survey of well-refined mononucleoside, mononucleotide, dinucleoside monophosphate, and trinucleoside diphosphate crystal structures found in the Cambridge Structural Database and the Nucleic Acid Database that appeared in The Journal of the American Chemical Society (Anke Gelbin, Bohdan Schneider, Lester Clowney, Shu-Hsin Hsieh, Wilma K. Olson, and Helen M. Berman. "Geometric Parameters in Nucleic Acids: Sugar Phosphate Constituents" (1996) 118, 519-529.)



The following tables are summaries of the bond lengths, angles, and torsion angles used in this summary.



Nitrogenous Bases

The following table contains the complete references for the structures used in a statistical survey of small molecules in the Cambridge Structural Database for high-resolution X-ray and neutron crystal structures that appeared in The Journal of the American Chemical Society (Lester Clowney, Shri C. Jain, A. R. Srinivasan, John Westbrook, Wilma K. Olson, and Helen M. Berman. (1996) J. Am. Chem. Soc. 118, 519-529.)
