Structural biology has come a long way, from being a niche interest of specialists to where we are today, with over 127,500 biomolecular structures available in the Protein Data Bank (PDB) as of the writing of this letter. The two main factors that have be ...
Effectors secreted by the type Ill secretion system are essential for bacterial pathogenesis. Members of the Yersinia outer-protein J (YopJ) family of effectors found in diverse plant and animal pathogens depend on a protease-like catalytic triad to acetyl ...
The radical SAM enzyme NosL catalyzes the conversion of L-Trp to 3-methyl-2-indolic acid, and this reaction is initiated by the 5'-deoxyadenosyl (dAdo) radical-mediated hydrogen abstraction from the L-Trp amino group. We demonstrate here that when D-Trp wa ...
Our recently solved high-resolution structure of the serotonin 5-HT3 receptor (5-HT3R) delivered the first detailed structural insights for a mammalian pentameric ligand-gated ion channel. Based on this structure, we here performed a total of 2.8-μs all-at ...
G protein-coupled receptors are recognized as one of the largest families of membrane proteins. Despite sharing a characteristic seven-transmembrane topology, G protein-coupled receptors regulate a wide range of cellular signaling pathways in response to v ...
G-protein-coupled receptors (GPCRs) are involved in a wide range of physiological processes, and they have attracted considerable attention as important targets for developing new medicines. A central and largely unresolved question in drug discovery, whic ...
Human purinergic Gprotein-coupled receptor P2Y(1) (P2Y(1)R) is activated by adenosine 5'-diphosphate (ADP) to induce platelet activation and thereby serves as an important antithrombotic drug target. Crystal structures of P2Y(1)R revealed that one ligand ( ...
The question how G-protein-coupled receptors transduce an extracellular signal by a sequence of transmembrane conformational transitions into an intracellular response remains to be solved at molecular detail. Herein, we use molecular dynamics simulations ...
G-protein-coupled receptors (GPCRs) are important targets for treating severe diseases. However why certain molecules act as activators whereas others, with similar structures, block GPCR activation, is poorly understood since the same molecule can activat ...
A multi-gene family of ~1000 G protein-coupled olfactory receptors (ORs) constitutes the molecular basis of mammalian olfaction. Due to the lack of structural data its remarkable capacity to detect and discriminate thousands of odorants remains poorly unde ...
