[NMR paper] Insights into the Structure of Invisible Conformations of Large Methyl Group Labeled Molecular Machines from High Pressure NMR
Insights into the Structure of Invisible Conformations of Large Methyl Group Labeled Molecular Machines from High Pressure NMR
Most proteins are highly flexible and can adopt conformations that deviate from the energetically most favorable ground state. Structural information on these lowly populated, alternative conformations is often lacking, despite the functional importance of these states. Here, we study the pathway by which the Dcp1:Dcp2 mRNA decapping complex exchanges between an autoinhibited closed and an open conformation. We make use of methyl Carr-Purcell-Meiboom-Gill (CPMG)...

[NMR paper] Protein-Ligand Binding Volume Determined from a Single 2D NMR Spectrum with Increasing Pressure
Protein-Ligand Binding Volume Determined from a Single 2D NMR Spectrum with Increasing Pressure
Proteins undergo changes in their partial volumes in numerous biological processes such as enzymatic catalysis, unfolding-refolding, and ligand binding. The change in the protein volume upon ligand binding-a parameter termed the protein-ligand binding volume-can be extensively studied by high-pressure NMR spectroscopy. In this study, we developed a method to determine the protein-ligand binding volume from a single two-dimensional (2D) ¹H-^(15)N heteronuclear single quantum coherence (HSQC)...

High-pressure methods for solving protein structures by X-ray crystallography and NMR are maturing. These techniques are beginning to impact our understanding of thermodynamic and structural features that define not only the protein's native conformation, but also the higher free energy conformations. The ability of...

High-pressure 15N/1H two-dimensional NMR spectroscopy has been utilized to study conformational fluctuation of a 76-residue protein ubiquitin at pH 4.5 at 20 degrees C. The on-line variable pressure cell technique is used in conjunction with a high-field NMR spectrometer operating at 750 MHz for 1H in the pressure...
