A comprehensive framework of E2–RING E3 interactions of the human ubiquitin–proteasome system

Molecular Systems Biology, 2009
Covalent attachment of ubiquitin to substrates is crucial to protein degradation, transcription regulation and cell signalling. Highly specific interactions between ubiquitin‐conjugating enzymes (E2) and ubiquitin protein E3 ligases fulfil essential ...

High-resolution NMR studies of antibiotics in cellular membranes

Nature Communications, 2018
Antibiotics that target the peptidoglycan precursor lipid II are promising templates for next-generation antibiotics. Here authors use solid-state NMR and monitor lipid II-binding antibiotics, such as nisin, directly in cell membranes.

Information-driven modeling of large macromolecular assemblies using NMR data [PDF]

, 2014
Availability of high-resolution atomic structures is one of the prerequisites for a mechanistic understanding of biomolecular function. This atomic information can, however, be difficult to acquire for interesting systems such as high molecular weight ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Early Stage Diagnosis of Oral Cancer Using 1H NMR–Based Metabolomics

Neoplasia: An International Journal for Oncology Research, 2009
Oral cancer is the eighth most common cancer worldwide and represents a significant disease burden. If detected at an early stage, survival from oral cancer is better than 90% at 5 years, whereas late stage disease survival is only 30%.

Direct observation of dynamic protein interactions involving human microtubules using solid-state NMR spectroscopy

Nature Communications, 2020
Microtubule (MT) organization is regulated by many microtubule-associated proteins (MAPs) that contain intrinsically disordered regions. Here authors produce [13C, 15N] labeled, functional microtubules from human cells for solid-state NMR which allows ...

Dynamic Nuclear Polarization NMR Spectroscopy: Revealing Multiple Conformations in Lipid-Anchored Peptide Vaccines [PDF]

, 2013
Sensitivity is the key: Dynamic nuclear polarization NMR spectroscopy provides structural information on liposomal vaccines targeting Alzheimer's disease. DMPC/DMPG/Cholesterol mainly stabilizes extended structures of the lipid-anchored peptide, while in

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Molecular action of NZ2114, a superior plectasin derivative

npj Antimicrobials and Resistance
NZ2114 is a triple-mutant of the natural peptide antibiotic plectasin that targets the peptidoglycan precursor molecule Lipid II using a supramolecular action, involving assembly of plectasin-Lipid II complexes in a large oligomeric structure, that is ...

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
