On the selection and design of proteins and peptide derivatives for the production of photoluminescent, red-emitting gold quantum clusters [PDF]

open access: yes, 2013
Novel pathways of the synthesis of photoluminescent gold quantum clusters (AuQCs) using biomolecules as reactants provide biocompatible products for biological imaging techniques.

A phenomenological model of non-genomic variability of luminescent bacterial cells

open access: yesВавиловский журнал генетики и селекции, 2023
The light emitted by a luminescent bacterium serves as a unique native channel of information regarding the intracellular processes within the individual cell.

Site-Directed Mutagenesis and Site-Specific Binding Analysis of Calmodulin (CaM) [PDF]

open access: yes, 2017
Calcium signaling is a major regulatory system in cells and a crucial part of cell biology. An important element in the decoding of intracellular calcium concentration into downstream processes is the ubiquitous and highly conserved calcium binding ...

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

open access: yesFrontiers 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,

Glucose sensor based on the LUQUEN-principle [PDF]

open access: yes, 1992
A new type of glucose sensor based on luminescence quenching (LUQUEN) is proposed. In this LUQUEN principle the concentration induced quenching is enlarged by radiationless (excited-state) energy transfer within the luminescent material.

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

open access: yesBMC 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

Mathematical model of the Lux luminescence system in the terrestrial bacterium Photorhabdus luminescens. [PDF]

open access: yes, 2009
A mathematical model of the Lux luminescence system, governed by the operon luxCDABE in the terrestrial bacterium Photorhabdus luminescens, was constructed using a set of coupled ordinary differential equations.

Direction dependent mechanical unfolding and Green Fluorescent Protein as a force sensor [PDF]

open access: yesPhysical Review E 84, 021918 (2011), 2011
An Ising--like model of proteins is used to investigate the mechanical unfolding of the Green Fluorescent Protein along different directions. When the protein is pulled from its ends, we recover the major and minor unfolding pathways observed in experiments.

Luminescent Metal Nanoclusters for Potential Chemosensor Applications

open access: yesChemosensors, 2017
Studies of metal nanocluster (M-NCs)-based sensors for specific analyte detection have achieved significant progress in recent decades. Ultra-small-size (<2 nm) M-NCs consist of several to a few hundred metal atoms and exhibit extraordinary physical ...

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

open access: yesScientific 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.
