Default Probing the intracellular glutathione redox potential by in-cell NMR spectroscopy.

Probing the intracellular glutathione redox potential by in-cell NMR spectroscopy.

Related Articles Probing the intracellular glutathione redox potential by in-cell NMR spectroscopy.

Angew Chem Int Ed Engl. 2014 Jan 7;53(2):447-50

Authors: Rhieu SY, Urbas AA, Bearden DW, Marino JP, Lippa KA, Reipa V

Abstract
Non-invasive and real-time analysis of cellular redox processes has been greatly hampered by lack of suitable measurement techniques. Here we describe an in-cell nuclear magnetic resonance (NMR) based method for measuring the intracellular glutathione redox potential by direct and quantitative measurement of isotopically labeled glutathione introduced exogenously into living yeast. By using this approach, perturbations in the cellular glutathione redox homeostasis were also monitored as yeast cells were subjected to oxidative stress.

Redox-dependent conformational changes in eukaryotic cytochromes revealed by paramagnetic NMR spectroscopy
Redox-dependent conformational changes in eukaryotic cytochromes revealed by paramagnetic NMR spectroscopy Abstract Cytochrome c (Cc) is a soluble electron carrier protein, transferring reducing equivalents between Cc reductase and Cc oxidase in eukaryotes. In this work, we assessed the structural differences between reduced and oxidized Cc in solution by paramagnetic NMR spectroscopy. First, we have obtained nearly-complete backbone NMR resonance assignments for iso-1-yeast Cc and horse Cc in both oxidation states. These were further used to derive pseudocontact shifts (PCSs) arising...
