Protein Model and Function Analysis in Quorum-Sensing Pathway of Vibrio qinghaiensis sp.-Q67

Biology, 2021
Bioluminescent bacteria are mainly found in marine habitats. Vibrio qinghaiensis sp.-Q67 (Q67), a nonpathogenic freshwater bacterium, has been a focus due to its wide use in the monitoring of environmental pollution and the assessment of toxicity ...

Fokker–Planck Analysis of Superresolution Microscopy Images

Mathematical and Computational Applications, 2023
A method for the analysis of super-resolution microscopy images is presented. This method is based on the analysis of stochastic trajectories of particles moving on the membrane of a cell with the assumption that this motion is determined by the ...

Self-calibrated magnetic aptamer sensor with dual Lanthanide-assisted Time-resolved luminescence for high-sensitive detection of melanoma exosomal PD-L1

Materials & Design, 2023
Highly sensitive detection of melanoma-derived exosomal PD-L1 plays a key role in non-invasive diagnosis of melanoma. Here, we proposed a self-calibrated magnetic aptamer sensor (sCMAS) for sensitive detection of melanoma exosomal PD-L1, using the dual ...

A simple and high-sensitivity method for analysis of ubiquitination and polyubiquitination based on wheat cell-free protein synthesis

BMC Plant Biology, 2009
Background Ubiquitination is mediated by the sequential action of at least three enzymes: the E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme) and E3 (ubiquitin ligase) proteins. Polyubiquitination of target proteins is also implicated

Control of actin polymerization via reactive oxygen species generation using light or radiation

Frontiers in Cell and Developmental Biology, 2022
Actin is one of the most prevalent proteins in cells, and its amino acid sequence is remarkably conserved from protozoa to humans. The polymerization-depolymerization cycle of actin immediately below the plasma membrane regulates cell function, motility,

Design of an artificial phage-display library based on a new scaffold improved for average stability of the randomized proteins

Scientific Reports, 2023
Scaffold-based protein libraries are designed to be both diverse and rich in functional/folded proteins. However, introducing an extended diversity while preserving stability of the initial scaffold remains a challenge.

Bioluminescent monitoring of recombinant lactic acid bacteria and their products

mBio, 2023
Biotherapeutic strategies to promote health, including the application of engineered microbes to deliver therapeutic molecules, hold strong promise. However, without precision tools to detect therapeutic microbes and their products, we are hampered in ...
