Rational engineering of enzyme allosteric regulation through sequence evolution analysis.

open access: yesPLoS Computational Biology, 2012
Control of enzyme allosteric regulation is required to drive metabolic flux toward desired levels. Although the three-dimensional (3D) structures of many enzyme-ligand complexes are available, it is still difficult to rationally engineer an ...

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

open access: yesNature 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 ...

Allosteric regulation of rhomboid intramembrane proteolysis [PDF]

open access: yesThe EMBO Journal, 2014
AbstractProteolysis within the lipid bilayer is poorly understood, in particular the regulation of substrate cleavage. Rhomboids are a family of ubiquitous intramembrane serine proteases that harbour a buried active site and are known to cleave transmembrane substrates with broad specificity.

The calcium-sensing receptor as a regulator of cellular fate in normal and pathological conditions [PDF]

open access: yes, 2013
The calcium-sensing receptor (CaSR) belongs to the evolutionarily conserved family of plasma membrane G protein-coupled receptors (GPCRs). Early studies identified an essential role for the CaSR in systemic calcium homeostasis through its ability to ...

Binding leverage as a molecular basis for allosteric regulation.

open access: yesPLoS Computational Biology, 2011
Allosteric regulation involves conformational transitions or fluctuations between a few closely related states, caused by the binding of effector molecules.

Computational modeling of cAMP­-dependent protein kinase allostery [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2023
Allosteric regulation by ATP of peptide binding with a cAMP-dependent protein kinase catalytic subunit was com­putationally modeled by combining conventional docking analysis and molecular dynamics calculations.

Allosteric regulation of phenylalanine hydroxylase [PDF]

open access: yesArchives of Biochemistry and Biophysics, 2012
The liver enzyme phenylalanine hydroxylase is responsible for conversion of excess phenylalanine in the diet to tyrosine. Phenylalanine hydroxylase is activated by phenylalanine; this activation is inhibited by the physiological reducing substrate tetrahydrobiopterin.

Molecular basis for the allosteric activation mechanism of the heterodimeric imidazole glycerol phosphate synthase complex

open access: yesNature Communications, 2021
The allosteric regulation of the bienzyme complex imidazole glycerol phosphate synthase (HisFH) remains to be elucidated. Here, the authors provide structural insights into the dynamic allosteric mechanism by which ligand binding to the cyclase and ...

Engineering and exploiting synthetic allostery of NanoLuc luciferase

open access: yesNature 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 ...
