Counterions are vital for the structure and function of biomolecules. However, the behavior of counterions remains elusive due to the difficulty in characterizing mobile ions. Here, we demonstrate that the dynamics of cations around biological macromolecules can be revealed by ^(23)Na diffusion nuclear magnetic resonance (NMR) spectroscopy. NMR probe hardware capable of generating strong magnetic field gradients enables ^(23)Na NMR-based diffusion measurements for Na^(+) ions in solutions of...
[NMR paper] Dynamics properties of membrane proteins in native cell membranes revealed by solid-state NMR spectroscopy
Dynamics properties of membrane proteins in native cell membranes revealed by solid-state NMR spectroscopy
Cell membranes provide an environment that is essential to the functions of membrane proteins. Cell membranes are mainly composed of proteins and highly diverse phospholipids. The influence of diverse lipid compositions of native cell membranes on the dynamics of the embedded membrane proteins has not been examined. Here we employ solid-state NMR to investigate the dynamics of E. coli Aquaporin Z (AqpZ) in its native inner cell membranes, and reveal the influence of diverse lipid...
