Structural characterization of intrinsically disordered proteins by NMR spectroscopy. [PDF]

open access: yes, 2013
Recent advances in NMR methodology and techniques allow the structural investigation of biomolecules of increasing size with atomic resolution. NMR spectroscopy is especially well-suited for the study of intrinsically disordered proteins (IDPs) and ...

Consoramides A–C, New Zwitterionic Alkaloids from the Fungus Irpex consors

open access: yesMycobiology, 2021
In our ongoing search for new secondary metabolites from fungi, a basidiomycete fungus Irpex consors was selected for mycochemical investigation, and three new zwitterionic alkaloids (1-3) and five known compounds (4-8) were isolated from the culture ...

Exploiting periodic first-principles calculations in NMR spectroscopy of disordered solids [PDF]

open access: yes, 2013
Much of the information contained within solid-state nuclear magnetic resonance (NMR) spectra remains unexploited because of the challenges in obtaining high-resolution spectra and the difficulty in assigning those spectra.

An inter-laboratory comparison demonstrates that [H-1]-NMR metabolite fingerprinting is a robust technique for collaborative plant metabolomic data collection. [PDF]

open access: yes, 2010
In any metabolomics experiment, robustness and reproducibility of data collection is of vital importance. These become more important in collaborative studies where data is to be collected on multiple instruments.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

A new structural arrangement in proteins involving lysine NH3 + group and carbonyl

open access: yesScientific Reports, 2017
Screening of the Protein Data Bank led to identification of a recurring structural motif where lysine NH3 + group interacts with backbone carbonyl. This interaction is characterized by linear atom arrangement, with carbonyl O atom positioned on the three-

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Protein folding on the ribosome studied using NMR spectroscopy [PDF]

open access: yes, 2013
NMR spectroscopy is a powerful tool for the investigation of protein folding and misfolding, providing a characterization of molecular structure, dynamics and exchange processes, across a very wide range of timescales and with near atomic resolution.
