The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Single-Molecule FRET in Living Bacteria [PDF]
Biophysical Journal, 2012 Most single-molecule FRET experiments are performed in vitro, using tightly controlled conditions and well-defined concentrations of a limited number of interacting components. However, in order to understand biological mechanisms as they occur in vivo while simultaneously taking advantage of the extra information provided by single-molecule detection,

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome
FEBS Letters, EarlyView.In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

Single-Molecule FRET: Methods and Biological Applications
, 2009 Since the first single-molecule fluorescence resonance energy transfer (FRET) measurement in 1996, the technique has contributed substantially to our understanding of biological molecules and processes by probing the structure and dynamics of nucleic ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation
Molecular Oncology, EarlyView.How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Single Molecule FRET Characterization of Large Ribozyme Folding [PDF]
, 2012 A procedure to investigate the folding of group II intron by single molecule Fluorescence Resonance Energy Transfer (smFRET) using total internal reflection fluorescence microscopy (TIRFM) is described in this chapter. Using our previous studies on the folding and dynamics of a large ribozyme in the presence of metal ions (i.e., Mg2+ and Ca2+) and/or ...

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy
Molecular Oncology, EarlyView.LCOR (Ligand‐dependent corepressor) mRNA encapsulated in polymeric nanoparticles restores LCOR activity in tumor cells, constraining aggressive tumor cell states and increasing tumor immunogenicity. This reprogramming makes tumor cells more vulnerable to T‐cell attack and enhances their response to immune‐checkpoint immunotherapy.
