Abstract
Attachment of human noroviruses to histo blood group antigens is thought to be essential for infection of host cells. Molecular details of the attachment process can be studied in vitro using a variety of NMR experiments. The use of protein NMR based experiments requires assignments of backbone NMR signals. Using uniformly (2)H,(15)N-labeled protruding domains (P-dimers) of a prevalent epidemic human norovirus strain (GII.4 Saga) we have studied the potential of ?-l-fucose covalently linked to a rigid lanthanide binding tag to aid backbone assignments using the paramagnetic properties of lanthanide ions. The synthesis of tagged ?-l-fucose is reported. Notably, the metal chelating unit connects to the carbohydrate via a triazole linker constructed using click chemistry.

As time- and ensemble-averaged measures, NMR observables contain information about both protein structure and dynamics. This work represents a computational study to extract such information for membrane proteins from orientation-dependent NMR observables: solid-state NMR chemical shift anisotropy and dipolar coupling, and solution NMR...

Cys-Ph-TAHA: a lanthanide binding tag for RDC and PCS enhanced protein NMR
Abstract Here we present Cys-Ph-TAHA, a new nonadentate lanthanide tag for the paramagnetic labelling of proteins. The tag can be easily synthesized and is stereochemically homogenous over a wide range of temperatures, yielding NMR spectra with a single set of peaks. Bound to ubiquitin, it induced large residual dipolar couplings and pseudocontact shifts that could be measured easily and agreed very well with the protein structure. We show that Cys-Ph-TAHA can be used to label large proteins that are...
