NMR spectroscopy again confirmed that the structures of the wild type and mutants are not significantly affected by the deletions (Supplementary Fig. 9b). The effect of deleting loop-4 is particularly interesting as the equivalent region of KdHpuA, albeit being three residues shorter, is not ...

Observation of diastereomers of the hydrogen-bonded aggregate hub(M)_3.3CA using H nuclear magnetic resonance spectroscopy when CA is an optically-active isocyanuric acidDiastereomers of the hydrogen-bonded aggregate hub (M)_3.3CA (Chart 1) are observed in the ~1H NMR spectrum when the ...
NMR spectroscopy. An overview of the different steps involved in homology modeling follows, with emphasis on sources of errors and how they can be checked. Ultimately our goal is not to rank these methods but rather we hope to show that they all provide valuable and often complementary ...

‘And one of the most important, in my view, is Graham Ball’s work where he’s been able to use NMR spectroscopy at very low temperatures to actually identify and observe alkane–metal complexes, and to make extremely specific decisions about what the structures of the complexes really are...
