Abstract
PEGylated proteins are widely used in biomedicine but, in spite of their importance, no atomic-level information is available since they are generally resistant to structural characterization approaches. PEGylated proteins are shown here to yield highly resolved solid-state NMR spectra, which allows assessment of the structural integrity of proteins when PEGylated for therapeutic or diagnostic use.

Study of PEGylated model protein reveals porous structure based on PEG size
Phys.Org
NMR studies using 1H-15N heteronuclear single-quantum correlation spectroscopy showed that the PEG-Pc had well-dispersed resonances that indicated the protein remained folded in a stable conformation. Chemical shift perturbations were only...

Abstract
The native environment for a membrane protein is a phospholipid bilayer. Because the protein is immobilized on NMR timescales by the interactions within a bilayer membrane, solid-state NMR methods are essential to obtain high-resolution spectra. Approaches have been developed for both unoriented and oriented samples, however, they all rest on the foundation of the most fundamental...

Abstract
Solid-state NMR spectroscopy proved to be a versatile tool for characterization of structure and dynamics of complex biochemical systems. In particular, magic angle spinning (MAS) solid-state NMR came to maturity for application towards structural elucidation of biological macromolecules. Current challenges in applying solid-state NMR as well as progress achieved...

Fold it: Solid-state NMR unravels proteins
Researchers have developed a novel solid-state NMR spectroscopic method that uses paramagnetic tags to help them visualize the shape of protein molecules. The technique could be used to help scientists understand the properties of various biological molecules under normal, healthy conditions and also in those that are involved in a range of diseases.

Authors: Bertini I, Luchinat C, Parigi G, Ravera E, Reif B, Turano P
Relatively large proteins in solution, spun in NMR rotors for solid samples at typical ultracentrifugation speeds, sediment at the rotor wall. The sedimented proteins provide high-quality solid-state-like NMR spectra suitable for structural investigation. The proteins fully revert to the native solution state when...
