Solid-state NMR spectroscopy [PDF]

open access: yesNature Reviews Methods Primers, 2021
Solid-state nuclear magnetic resonance (NMR) spectroscopy is an atomic-level method used to determine the chemical structure, three-dimensional structure, and dynamics of solids and semi-solids. This Primer summarizes the basic principles of NMR as applied to the wide range of solid systems.

The molecular pH-response mechanism of the plant light-stress sensor PsbS

open access: yesNature Communications, 2021
Photosystem II subunit S (PsbS) senses thylakoid lumen acidification when plants are exposed to excess light. Here the authors use NMR and IR spectroscopy to show that low pH causes repositioning of an amphipathic helix and folding of a loop involving ...
