Conformational flexibility influences structure–function relationships in tyrosyl protein sulfotransferase-2 [PDF]

open access: yes, 2016
Tyrosine sulfation is a very important posttranslational modification of proteins. It is catalyzed by tyrosylprotein sulfotransferase and recently became increasingly important for biomedicine and pharmacy.

Protein dynamics and conformational selection in bidirectional signal transduction

open access: yesBMC Biology, 2012
Protein conformational dynamics simultaneously allow promiscuity and specificity in binding. The multiple conformations of the free EphA4 ligand-binding domain observed in two new EphA4 crystal structures provide a unique insight into the conformational ...

Molecular dynamics simulation study of the binding of purine bases to the aptamer domain of the guanine sensing riboswitch [PDF]

open access: yes, 2009
Riboswitches are a novel class of genetic control elements that function through the direct interaction of small metabolite molecules with structured RNA elements.

ABCE1 Controls Ribosome Recycling by an Asymmetric Dynamic Conformational Equilibrium

open access: yesCell Reports, 2019
Summary: The twin-ATPase ABCE1 has a vital function in mRNA translation by recycling terminated or stalled ribosomes. As for other functionally distinct ATP-binding cassette (ABC) proteins, the mechanochemical coupling of ATP hydrolysis to conformational

Protein conformational transitions coupling with ligand interactions: Simulations from molecules to medicine

open access: yesMedicine in Novel Technology and Devices, 2019
The functions and activities of proteins are closely related to their structures and dynamics, and their interactions with ligands. Knowledge of the mechanistic events of proteins’ conformational transitions and interactions with ligands is crucially ...

Laboratory evolution of protein conformational dynamics

open access: yes, 2018
This review focuses on recent work that has begun to establish specific functional roles for protein conformational dynamics, specifically how the conformational landscapes that proteins can sample can evolve under laboratory based evolutionary selection.

Mapping the conformational energy landscape of Abl kinase using ClyA nanopore tweezers

open access: yesNature Communications, 2022
Quantitative characterization of kinase conformational dynamics remains challenging. Here, the authors show that protein nanopore tweezers allow analyzing the conformational energy landscape and ligand binding of the Abl kinase domain.

Distance-Based Configurational Entropy of Proteins from Molecular Dynamics Simulations. [PDF]

open access: yesPLoS ONE, 2015
Estimation of configurational entropy from molecular dynamics trajectories is a difficult task which is often performed using quasi-harmonic or histogram analysis.

Characterisation of HOIP RBR E3 ligase conformational dynamics using integrative modelling

open access: yesScientific Reports, 2022
Multidomain proteins composed of individual domains connected by flexible linkers pose a challenge for structural studies due to their intrinsic conformational dynamics.

Intrinsic determinants of prion protein neurotoxicity in Drosophila: from sequence to (dys)function

open access: yesFrontiers in Molecular Neuroscience, 2023
Prion diseases are fatal brain disorders characterized by deposition of insoluble isoforms of the prion protein (PrP). The normal and pathogenic structures of PrP are relatively well known after decades of studies.
