The heightened dipolar interactions in solids render solid-state NMR (ssNMR) spectra more difficult to interpret than solution NMR spectra. On the other hand, ssNMR does not suffer from severe molecular weight limitations like solution NMR. In recent years, ssNMR has undergone rapid technological developments that have enabled structure-function studies of increasingly larger biomolecules, including membrane proteins. Current methodology includes stable isotope labeling schemes, non-uniform...
[NMR paper] Solid state NMR chemical shift assignment of the non-structural single-stranded DNA binding protein gVp from fd bacteriophage
Solid state NMR chemical shift assignment of the non-structural single-stranded DNA binding protein gVp from fd bacteriophage
The non-structural gene V protein (pV, gVp) from fd virus is a non-specific single-stranded DNA binding protein. The role of gVp is to sequester the single-stranded DNA thus reducing the generation of the replicative DNA form and leading to the formation of progeny phage. In this study, we assigned the ^(13)C and ^(15)N resonances of the crystalline unbound protein by magic-angle spinning solid-state NMR. The secondary structure predicted by the NMR shifts is in...

Rapid automated determination of chemical shift anisotropy values in the carbonyl and carboxyl groups of fd-y21m bacteriophage using solid state NMR
Rapid automated determination of chemical shift anisotropy values in the carbonyl and carboxyl groups of fd-y21m bacteriophage using solid state NMR
Abstract
Determination of chemical shift anisotropy (CSA) in immobilized proteins and protein assemblies is one of several tools to determine protein dynamics on the timescales of microseconds and faster. The large CSA values of C=O groups in the rigid limit makes them in particular attractive for measurements of large amplitude motions, or their absence. In this study, we implement a 3D...

Probabilistic validation of protein NMR chemical shift assignments
Abstract
Data validation plays an important role in ensuring the reliability and reproducibility of studies. NMR investigations of the functional properties, dynamics, chemical kinetics, and structures of proteins depend critically on the correctness of chemical shift assignments. We present a novel probabilistic method named ARECA for validating chemical shift assignments that relies on the nuclear Overhauser effect data . ARECA has been evaluated through its application to 26...

A probabilistic approach for validating protein NMR chemical shift assignments
Abstract It has been estimated that more than 20% of the proteins in the BMRB are improperly referenced and that about 1% of all chemical shift assignments are mis-assigned. These statistics also reflect the likelihood that any newly assigned protein will have shift assignment or shift referencing errors. The relatively high frequency of these errors continues to be a concern for the biomolecular NMR community. While several programs do exist to detect and/or correct chemical shift mis-referencing or chemical shift mis-assignments, most can only do one, or the other. The one program...
