Computational Analysis of Residue Interaction Networks and Coevolutionary Relationships in the Hsp70 Chaperones: A Community-Hopping Model of Allosteric Regulation and Communication. [PDF]

PLoS Computational Biology, 2017
Allosteric interactions in the Hsp70 proteins are linked with their regulatory mechanisms and cellular functions. Despite significant progress in structural and functional characterization of the Hsp70 proteins fundamental questions concerning modularity

Prospects for the use of allosteric drugs in real-world clinical practice

Реальная клиническая практика: данные и доказательства, 2023
While the clinical validity of the use of allosteric regulation is known, scientists are working on the discovery of new methods for the development of allosteric drugs that can modulate the functions of enzymes, depending on the desired therapeutic ...

Novel allosteric inhibition of phosphoribulokinase identified by ensemble kinetic modeling of Synechocystis sp. PCC 6803 metabolism

Metabolic Engineering Communications, 2020
The present study attempted a computer simulation of the metabolism of a model cyanobacteria, Synechocystis sp. PCC 6803 (PCC 6803) to predict allosteric inhibitions that are likely to occur in photoautotrophic and mixotrophic conditions as well as in a ...

Design, Synthesis and Characterization of a New Series of Fluorescent Metabotropic Glutamate Receptor Type 5 Negative Allosteric Modulators

Molecules, 2020
In recent years, new drug discovery approaches based on novel pharmacological concepts have emerged. Allosteric modulators, for example, target receptors at sites other than the orthosteric binding sites and can modulate agonist-mediated activation ...

Allosteres to regulate neurotransmitter sulfonation [PDF]

Journal of Biological Chemistry, 2019
Catecholamine neurotransmitter levels in the synapses of the brain shape human disposition-cognitive flexibility, aggression, depression, and reward seeking-and manipulating these levels is a major objective of the pharmaceutical industry. Certain neurotransmitters are extensively sulfonated and inactivated by human sulfotransferase 1A3 (SULT1A3).

Light-regulated allosteric switch enables temporal and subcellular control of enzyme activity

eLife, 2020
Engineered allosteric regulation of protein activity provides significant advantages for the development of robust and broadly applicable tools. However, the application of allosteric switches in optogenetics has been scarce and suffers from critical ...

Functional selectivity of insulin receptor revealed by aptamer-trapped receptor structures

Nature Communications, 2022
DNA aptamers can activate insulin receptor as selective agonists or positive allosteric modulators. Here, authors determine structures of the insulin receptor bound to aptamers and provide a basis for the selective activation or allosteric regulation of ...

Engineering and exploiting synthetic allostery of NanoLuc luciferase

Nature Communications, 2022
Allosteric regulation of proteins allows transduction and interconversion of biochemical signals. Here the authors construct an allosteric version of circular permutated NanoLuc that can be activated by a ligand; they use this to create biosensors to ...
