A New Strategy for Atomic Flexible Fitting in Cryo-EM Maps by Molecular Dynamics with Excited Normal Modes (MDeNM-EMfit)

Previous studies demonstrated the efficiency of the Molecular Dynamics with excited Normal Modes (MDeNM) method on the characterization of large structural changes at a low computational cost. We present here MDeNM-EMfit, an extension of the…

Gold nanorods-based oligonucleotides carrier quantitative characterisation

Gold nanorods (GNRs) are attracting a lot of attention due to their extraordinary optical properties, and potential use for medical applications. The issue of the attachment of double stranded oligonucleotides onto GNR surfaces is crucial for the…

SUGT1 controls susceptibility to HIV-1 infection by stabilizing microtubule plus-ends

Understanding the viral-host cell interface during HIV-1 infection is a prerequisite for the development of innovative antiviral therapies. Here we show that the suppressor of G2 allele of skp1 (SUGT1) is a permissive factor for human…

Design of Light-Sensitive Triggers for Endothelial NO-Synthase Activation

A specific light trigger for activating endothelial Nitric Oxide-Synthase (eNOS) in real time would be of unique value to decipher cellular events associated with eNOS activation or to generate on demand cytotoxic levels of NO at specific sites for…

Impact of pulsed electric fields and mechanical compressions on the permeability and structure of Chlamydomonas reinhardtii cells

Current research findings clearly reveal the role of the microalga's cell wall as a key obstacle to an efficient and optimal compound extraction. Such extraction process is therefore closely related to the microalga species used. Effects of…

Discovery, SAR study and ADME properties of methyl 4-amino-3-cyano-1-(2-benzyloxyphenyl)-1 H -pyrazole-5-carboxylate as an HIV-1 replication inhibitor

(ESI) available: . See Inspired by the antiviral activity of known pyrazole-based HIV inhibitors, we screened our in-house library of pyrazole-based compounds to evaluate their in cellulo activity against HIV-1 replication. Two hits with very…

Recognition of different base tetrads by RHAU (DHX36): X-ray crystal structure of the G4 recognition motif bound to the 3'-end tetrad of a DNA G-quadruplex

G-quadruplexes (G4) are secondary structures of nucleic acids that can form in cells and have diverse biological functions. Several biologically important proteins interact with G-quadruplexes, of which RHAU - a helicase from the DEAH-box…
