  • Cosy, Noesy, and HoHaHa! Respectively, these are abbreviations for two-dimensional scalar correlated spectroscopy, two-dimensional nuclear Overhauser enhancement spectroscopy, and Homonuclear Hartmann Hahn transfer experiment - three of the techniques used to study Megasphaera elsdenii. Apparently, we need to learn well the general rules for two-dimensional nuclear magnetic resonance (NMR) determination of atomic connectivities and three-dimensional polypeptide structures. Assignment of the 1H NMR resonances of the 137 amino acid residues of flavodoxin is a good lesson as well as a careful example of the power of two-dimensional NMR structural determinations for noncrystalline proteins.
