AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The work presented focuses on the analysis of a police investigation implemented in the computing environment SCY-Lab. The prime objective is to check if the implementation of the situation helps pupils change their conceptions concerning the DNA molecule ...
O6-alkylguanine-DNA alkyltransferase (AGT) adopts a non-enzymatic suicide mechanism for the repair of methylated guanine bases by transferring the methyl adduct to itself, thereby initiating unfolding and fast degradation. Classical molecular dynamics simu ...
Global linear and nonlinear bifurcation analysis is used to revisit the spiral vortex breakdown of nominally axisymmetric swirling jets. For the parameters considered herein, stability analyses single out two unstable linear modes of azimuthal wavenumber m ...
Conformationally constrained peptide ligands offer an attractive format for the development of therapeutics. They can bind with high affinity and selectivity to protein targets, they are small enough to diffuse into tissues, they can be synthesized chemica ...
Interactions of transmembrane (TM) helices play a key role in many cell processes. The configuration and cross angle these helices adopt are traditionally attributed to specific residue interactions. We present a different approach, in which specific resid ...
The thermosensor histidine kinase DesK from Bacillus subtilis senses changes in membrane fluidity initiating an adaptive response. Structural changes in DesK have been implicated in transmembrane signaling, but direct evidence is still lacking. On the basi ...
Gene product 5 (gp5) of bacteriophage T4 is a spike-shaped protein that functions to disrupt the membrane of the target cell during phage infection. Its C-terminal domain is a long and slender -helix that is formed by three polypeptide chains wrapped aroun ...
The physical chemistry of bio molecules in the gas phase is progressing at a rapid pace. One of the most promising areas is the determination of the conformations of biologically important molecules. Quantitative determination of their relative energies is ...
The packing structures of transmembrane helices are traditionally attributed to patterns in residues along the contact surface. In this view, besides keeping the helices confined in the membrane, the bilayer has only a minor effect on the helices structure ...
Microsecond molecular dynamics simulations of B-DNA oligomers carried out in an aqueous environment with a physiological salt concentration enable us to perform a detailed analysis of how potassium ions interact with the double helix. The oligomers studied ...
