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.

Time-resolved burst variance analysis

open access: yesBiophysical Reports, 2023
Quantifying biomolecular dynamics has become a major task of single-molecule fluorescence spectroscopy methods. In single-molecule Förster resonance energy transfer (smFRET), kinetic information is extracted from the stream of photons emitted by attached

Fluorescence lifetime analysis of smFRET with contribution of PIFE on donor and acceptor

open access: yesbioRxiv, 2023
Single-molecule fluorescence resonance energy transfer (FRET) is a powerful technique based on dipole-dipole interaction between donor and acceptor fluorophores to observe inter- and intra-molecular dynamics in realtime with sensitivity to macro ...

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).

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.

Observation of structural switch in nascent SAM-VI riboswitch during transcription at single-nucleotide and single-molecule resolution

open access: yesNature Communications, 2023
Growing RNAs fold differently as they are transcribed, which modulates their finally adopted structures. Riboswitches regulate gene expression by structural change, which are sensitive to co-transcriptionally structural biology.

Crowding-induced hybridization of single DNA hairpins [PDF]

open access: yes, 2015
It is clear that a crowded environment influences the structure, dynamics, and interactions of biological molecules, but the complexity of this phenomenon demands the development of new experimental and theoretical approaches.

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 ...

Impact of Molecule Concentration, Diffusion Rates and Surface Passivation on Single-Molecule Fluorescence Studies in Solution

open access: yesBiomolecules, 2022
For single-molecule studies in solution, very small concentrations of dye-labelled molecules are employed in order to achieve single-molecule sensitivity.
