  • A biosensor to gauge protein homeostasis resilience differences in the nucleus compared to cytosol of mammalian cells

    • Authors : Raeburn, Candice B. (2021)

  • An extensive network of chaperones and other proteins maintain protein homeostasis and guard against inappropriate protein aggregation that is a hallmark of neurodegenerative diseases. Using a fluorescence resonance energy-based biosensor that simultaneously reports on intact cellular chaperone holdase activity and detrimental aggregation propensity, we investigated the buffering capacity of the systems managing protein homeostasis in the nucleus of the human cell l...

  • The role of glutathione in periplasmic redox homeostasis and oxidative protein folding in Escherichia coli

    • Authors : Knoke, Lisa R. (2023)

  • The thiol redox balance in the periplasm of E. coli depends on the DsbA/B pair for oxidative 14 power and the DsbC/D system as its complement for isomerization of non-native disulfides. 15 While the standard redox potentials of those systems are known, the in vivo redox potential 16 imposed onto protein thiol disulfide pairs in the periplasm remains unknown. Here, we used 17 genetically encoded redox probes (roGFP2 ...
