NMR analysis of 15N-labeled naphthyridine carbamate dimer (NCD) to contiguous CGG/CGG units in DNA

The structure of the complex formed by naphthyridine carbamate dimer (NCD) binding to CGG repeat sequences in DNA, associated with fragile X syndrome, has been elucidated using 15N-labeled NCD and 1H–15N HSQC. In a fully saturated state, two NCD molecules consistently bind to each CGG/CGG unit, main...

Description
Summary:The structure of the complex formed by naphthyridine carbamate dimer (NCD) binding to CGG repeat sequences in DNA, associated with fragile X syndrome, has been elucidated using 15N-labeled NCD and 1H–15N HSQC. In a fully saturated state, two NCD molecules consistently bind to each CGG/CGG unit, maintaining a 1 : 2 binding stoichiometry.
