Preparation of Cell-free Synthesized Proteins Selectively Double Labeled for Single-molecule FRET Studies

open access: yesBio-Protocol, 2018
Single-molecule FRET (smFRET) is a powerful tool to investigate molecular structures and conformational changes of biological molecules. The technique requires protein samples that are site-specifically equipped with a pair of donor and acceptor ...

Altered tRNA dynamics during translocation on slippery mRNA as determinant of spontaneous ribosome frameshifting

open access: yesNature Communications, 2022
Slippery sequences in mRNA can cause the ribosome to change its reading frame. Using smFRET, Poulis et al. show how reversible fluctuations of peptidyl-tRNA slow down translocation, alter ribosome dynamics, and favor spontaneous ribosome frameshifting.

Effects of DNA looping behavior using smFRET

open access: yes, 2023
This study developed a single-molecule-based assay to track the looping (circularization) of individual double-stranded DNA (dsDNA) molecules in real time. DNA encodes our genetic information through a unique combination of four nucleotides: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Deep-LASI: deep-learning assisted, single-molecule imaging analysis of multi-color DNA origami structures

open access: yesNature Communications, 2023
Single-molecule experiments have changed the way we explore the physical world, yet data analysis remains time-consuming and prone to human bias. Here, we introduce Deep-LASI (Deep-Learning Assisted Single-molecule Imaging analysis), a software suite ...

Observation of long-range tertiary interactions during ligand binding by the TPP riboswitch aptamer

open access: yeseLife, 2015
The thiamine pyrophosphate (TPP) riboswitch is a cis-regulatory element in mRNA that modifies gene expression in response to TPP concentration. Its specificity is dependent upon conformational changes that take place within its aptamer domain.

The cytoplasmic synthesis and coupled membrane translocation of eukaryotic polyphosphate by signal-activated VTC complex

open access: yesNature Communications, 2023
The VTC complex generate eukaryotic polyphosphate (polyP). Authors here reveal how the signal-activated VTC synthesize cytosolic polyP and transport polyP across vacuolar membrane into the lumen, by using cryo-EM, in-cell NMR, and smFRET analyses.

Allosteric modulators enhance agonist efficacy by increasing the residence time of a GPCR in the active state

open access: yesNature Communications, 2021
Here, the authors use smFRET to assess the structural dynamics of metabotropic glutamate receptor mGlu2 and show that a positive allosteric modulator or the Gi protein stabilize mGlu2 in the glutamate-induced active state, leading to the full activation ...

High-Resolution smFRET in a Microfluidic Gas Exchange Platform [PDF]

open access: yesBiophysical Journal, 2010
Single-molecule Forster Resonance Energy Transfer (smFRET) is a powerful technique providing new insights in the physics and chemistry of bio-molecules. The smFRET signal quality depends on the photon-flux that can be harvested from the fluorescent dyes.
