Cell signaling, post-translational protein modifications and NMR spectroscopy
Abstract Post-translationally modified proteins make up the majority of the proteome and establish, to a large part, the impressive level of functional diversity in higher, multi-cellular organisms. Most eukaryotic post-translational protein modifications (PTMs) denote reversible, covalent additions of small chemical entities such as phosphate-, acyl-, alkyl- and glycosyl-groups onto selected subsets of modifiable amino acids. In turn, these modifications induce highly specific changes in the chemical ...

A simple design for anin situ, three-electrode spectroelectrochemical cell is reported that can be used in commercial Q- and W-band (ca. 34 and 94 GHz, respectively) electron paramagnetic resonance (EPR) spectrometers, using standard sample tubing (1.0 and 0.5 mm inner diameter, respectively) and within variable temperature cryostat systems....

The role of a protein inside a cell is determined by both its location and its conformational state. Although fluorescence techniques are widely used to determine the cellular localization of proteins in vivo, these approaches cannot provide detailed information about a protein's three-dimensional state. This gap, however, can be filled by NMR spectroscopy, which can be used to investigate both...

Mapping structural interactions using in-cell NMR spectroscopy (STINT-NMR)
David S Burz, Kaushik Dutta, David Cowburn & Alexander Shekhtman
We describe a high-throughput in-cell nuclear magnetic resonance (NMR)-based method for mapping the structural changes that accompany protein-protein interactions (STINT-NMR). The method entails sequentially expressing two (or more) proteins within a single bacterial cell in a time-controlled manner and monitoring the protein interactions using in-cell NMR spectroscopy. The resulting spectra provide a complete titration of the interaction and define...
