2H-DNP-enhanced 2H-13C solid-state NMR correlation spectroscopy.
Perdeuteration of biological macromolecules for magic angle spinning solid-state NMR spectroscopy can yield high-resolution (2)H-(13)C correlation spectra and the method is therefore of great interest for the structural biology community. Here we demonstrate that the combination of sample deuteration and dynamic nuclear polarization yields resolved (2)H-(13)C correlation spectra with a signal e...
متن کاملBolalipid membrane structure revealed by solid-state 2H NMR spectroscopy.
Membranes made from three specifically deuterium-labeled ether-linked bolalipids, [1',1',20',20'-2H4]C20BAS-PC, [2',2',19',19'-2H4]C20BAS-PC, or [10',11'-2H2]C20BAS-PC, were analyzed by 2H NMR spectroscopy. Unlike more common monopolar, ester-linked phospholipids, C20BAS-PC exhibits a high degree of orientational order throughout the membrane and the sn-1 chain of the lipid initially penetrates...
متن کاملAssessing the effects of time and spatial averaging in 15N chemical shift/15N-1H dipolar correlation solid state NMR experiments.
The effect of time and spatial averaging on (15)N chemical shift/(1)H-(15)N dipolar correlation spectra, i.e., PISEMA spectra, of alpha-helical membrane peptides and proteins is investigated. Three types of motion are considered: (a) Librational motion of the peptide planes in the alpha-helix; (b) rotation of the helix about its long axis; and (c) wobble of the helix about a nominal tilt angle....
