Synthesis and structure elucidation of five new pyrimido[5,4‐c]quinoline‐4(3H)‐one derivatives using 1D and 2D NMR spectroscopy

Five new 2?(amino/aroxy)?5?methylpyrimido[5,4?c]quinolin?4(3H)?one derivatives have been designed and synthesized via an aza?

NMR spectroscopic filtration of polypeptides and proteins in complex mixtures

Due to the inherent complexity of the natural biological environment, most studies on polypeptides, proteins and nucleic acids have so far been performed in vitro, away from physiologically relevant conditions.

Identification of a novel structure in heparin generated by potassium permanganate oxidation

The worldwide heparin contamination crisis in 2008 led health authorities to take fundamental steps to better control heparin manufacture, including implementing appropriate analytical and bio-analytical methods to ensure production and release of high quality heparin sodium product.

Root-mean-square-deviation-based rapid backbone resonance assignments in proteins

We have shown that the methodology based on the estimation of root-mean-square deviation (RMSD) between two sets of chemical shifts is very useful to rapidly assign the spectral signatures of 1HN, 13C?, 13C?, 13C', 1H?

Macromolecular NMR spectroscopy for the non‐spectroscopist

NMR spectroscopy is a powerful tool for studying the structure, function and dynamics of biological macromolecules. However, non?spectroscopists often find NMR theory daunting and data interpretation nontrivial. As the first of two back?to?back reviews on NMR spectroscopy aimed at non?

Ligands Turning Around in the Midst of Protein Conformers: The Origin of Ligand-Protein Mating. A NMR View

Protein-ligand binding is a puzzling process. Many theories have been devised since the pioneering key-and-lock hypothesis based on the idea that both the protein and the ligand have a rigid single conformation. Indeed, molecular motion is the essence of the universe.

Probing Protein Side Chain Dynamics Via 13C NMR Relaxation

Protein side chain dynamics is associated with protein stability, folding, and intermolecular interactions. Detailed dynamics information is crucial for the understanding of protein function and biochemical and biophysical properties, which can be obtained using NMR relaxation techniques.

Interaction of the replication terminator protein of Bacillus subtilis with DNA probed by NMR spectroscopy

Termination of DNA replication in Bacillus subtilis involves the polar arrest of replication forks by a specific complex formed between the dimeric 29kDa replication terminator protein (RTP) and DNA terminator sites. We have used NMR spectroscopy to probe the changes in 1H?
