Biological membrane structure by solid-state NMR.
Nuclear magnetic resonance (NMR) spectroscopy, and particularly solid-state NMR spectroscopy, is a method of choice to study the structure and dynamics of both the lipid and the protein components of model and biological membranes. Different approaches have been developed to study these systems in which the restricted molecular motions result in broad NMR spectra. This contribution will first p...
متن کاملStructure, chemical bonding, and 45Sc solid state NMR of Sc2RuSi2
The silicide Sc2RuSi2 was synthesized from the elements by arc-melting. The structure was refined on the basis of single crystal X-ray diffractometer data: Sc2CoSi2 type, * Manuscript Click here to view linked References
متن کاملSolid State NMR Studies of Structure and Dynamics in Systems
Deuterium NMR provides insight into dynamics over a wide range of kinetic rates. Experimental data can be rigorously fit and rates as well as motional mechanisms extracted. Temperatures dependent studies yield activation energies for key dynamic processes. Two model systems with well-characterized motions were studied to demonstrate this. The ammonium group in L-alanine has an activation energy...
متن کاملUnlocking the molecular structure of fungal melanin using 13C biosynthetic labeling and solid-state NMR.
Melanins are enigmatic pigments found in all biological kingdoms that are associated with a variety of functions, including microbial virulence. Despite being ubiquitous in nature, melanin pigments have long resisted atomic-level structural examination because of their insolubility and amorphous organization. Cryptococcus neoformans is a human pathogenic fungus that melanizes only when provided...
متن کاملSupramolecular structure of membrane-associated polypeptides by combining solid-state NMR and molecular dynamics simulations.
Elemental biological functions such as molecular signal transduction are determined by the dynamic interplay between polypeptides and the membrane environment. Determining such supramolecular arrangements poses a significant challenge for classical structural biology methods. We introduce an iterative approach that combines magic-angle spinning solid-state NMR spectroscopy and atomistic molecul...
