- W2321081387 abstract "A CHEMICAL STRUCTURE that has been sought for nearly 50 years—that of self-assembled 5'-guanosine monophosphate (5'-GMP)—has just been determined. The structure suggests how nucleotide monomers might line up to form covalently bonded nucleic acid oligomers and thus has potential implications for prebiotic chemistry. In 1962, David R. Davies and coworkers at the National Institutes of Health studied GMP assemblies. Their X-ray diffraction data showed that the nucleotides form G-quartets—planar sets of four hydrogen-bonded nucleotides—and suggested that the overall assemblies are helical. But the exact structure of these assemblies has remained unknown, despite efforts over the years by several groups to obtain it. Now, chemistry professor Gang Wu and grad student Irene C.M. Kwan of Queen’s University, in Kingston, Ontario, have determined the nuclear magnetic resonance structure of the assemblies in a solution containing sodium ions ( J.Am.Chem.Soc. , DOI:10.1021/ja809258y). The structure shows that G-quar..." @default.
