Comparing the intrinsic dynamics of multiple protein structures using elastic network models
Fuglebakk, Edvin; Tiwari, Sandhya Premnath; Reuter, Nathalie (Peer reviewed; Journal article, 2015-05)Background: Elastic network models (ENMs) are based on the simple idea that a protein can be described as a set of particles connected by springs, which can then be used to describe its intrinsic flexibility using, for ... -
Conformational Sampling and Nucleotide-Dependent Transitions of the GroEL Subunit Probed by Unbiased Molecular Dynamics Simulations
Skjærven, Lars; Grant, Barry; Muga, Arturo; Teigen, Knut; McCammon, J. Andrew; Reuter, Nathalie; Martinez, Aurora (Peer reviewed; Journal article, 2011-03-10)GroEL is an ATP dependent molecular chaperone that promotes the folding of a large number of substrate proteins in E. coli. Large-scale conformational transitions occurring during the reaction cycle have been characterized ... -
Dynamics-function relationship in the catalytic domains of N-terminal acetyltransferases
Abboud, Angèle; Bedoucha, Pierre; Byska, Jan; Arnesen, Thomas; Reuter, Nathalie (Journal article; Peer reviewed, 2020)N-terminal acetyltransferases (NATs) belong to the superfamily of acetyltransferases. They are enzymes catalysing the transfer of an acetyl group from acetyl coenzyme A to the N-terminus of polypeptide chains. N-terminal ... -
Interfacial Aromatics Mediating Cation-π Interactions with Choline-Containing Lipids Can Contribute as Much to Peripheral Protein Affinity for Membranes as Aromatics Inserted below the Phosphates
Waheed, Qaiser; Khan, Hanif Muhammad; He, Tao; Roberts, Mary F.; Gershenson, Anne; Reuter, Nathalie (Peer reviewed; Journal article, 2019)Membrane-binding interfaces of peripheral proteins are restricted to a small part of their exposed surface, so the ability to engage in strong selective interactions with membrane lipids at various depths in the interface, ... -
A model for hydrophobic protrusions on peripheral membrane proteins
Fuglebakk, Edvin; Reuter, Nathalie (Peer reviewed; Journal article, 2018-07-26)With remarkable spatial and temporal specificities, peripheral membrane proteins bind to biological membranes. They do this without compromising solubility of the protein, and their binding sites are not easily distinguished. ... -
Peptidomimetic inhibitors targeting the membrane-binding site of the neutrophil proteinase 3
Maximova, Ksenia; Reuter, Nathalie; Trylska, Joanna (Peer reviewed; Journal article, 2019)Proteinase 3 (PR3), together with other serine proteases, such as neutrophil elastase (NE) and cathepsin G (CG), regulates inflammatory and immune responses. However, in comparison with NE and CG, there is increasing ... -
