Structure of the human glucagon class B G-protein-coupled receptor
The crystal structure of the seven transmembrane helical domain of human GCGR is reported at 3.4 Å resolution, complemented by extensive site-specific mutagenesis, and a hybrid model of glucagon bound to GCGR to understand the molecular recognition of the receptor for its native ligand. Expand
Microscale thermophoresis quantifies biomolecular interactions under previously challenging conditions.
Flexibility in assay design qualifies MST for analysis of biomolecular interactions in complex experimental settings, which is demonstrated by addressing typically challenging types of binding events from various fields of life science. Expand
Structural Basis of Severe Acute Respiratory Syndrome Coronavirus ADP-Ribose-1″-Phosphate Dephosphorylation by a Conserved Domain of nsP3
Summary The crystal structure of a conserved domain of nonstructural protein 3 (nsP3) from severe acute respiratory syndrome coronavirus (SARS-CoV) has been solved by single-wavelength anomalousExpand
Crystal Structure of Nonstructural Protein 10 from the Severe Acute Respiratory Syndrome Coronavirus Reveals a Novel Fold with Two Zinc-Binding Motifs
Gel shift assays indicate that in isolation, nsp10 binds single- and double-stranded RNA and DNA with high-micromolar affinity and without obvious sequence specificity, suggesting that it is possible that nsp 10 functions within a larger RNA-binding protein complex. Expand
Ribonucleocapsid Formation of Severe Acute Respiratory Syndrome Coronavirus through Molecular Action of the N-Terminal Domain of N Protein
Electrostatic potential distribution on the surface of homology models of related coronaviral N-NTDs suggests that they use different modes of both RNA recognition and oligomeric assembly, perhaps explaining why their nucleocapsids have different morphologies. Expand
Nuclear Magnetic Resonance Structure of the N-Terminal Domain of Nonstructural Protein 3 from the Severe Acute Respiratory Syndrome Coronavirus
Structural similarities with proteins involved in various cell-signaling pathways indicate possible roles of nsp3a in viral infection and persistence. Expand
Proteomics Analysis Unravels the Functional Repertoire of Coronavirus Nonstructural Protein 3
A higher-resolution functional domain architecture for nsp3 is proposed that determines the interaction capacity of this protein, which is intimately associated with viral RNA in its role as a virion component. Expand
The role of a sodium ion binding site in the allosteric modulation of the A(2A) adenosine G protein-coupled receptor.
It is suggested that physiological concentrations of sodium ions affect functionally relevant conformational states of GPCRs and can help to design novel synthetic allosteric modulators or bitopic ligands exploiting the sodium ion binding pocket. Expand
Crystal Structure of a Monomeric Form of Severe Acute Respiratory Syndrome Coronavirus Endonuclease nsp15 Suggests a Role for Hexamerization as an Allosteric Switch
The hypothesis that absence of an adjacent monomer due to deletion of the hexamerization domain is the most likely cause for disruption of the active site of SARS-CoV is supported, offering a structural basis for why only thehexameric form of this enzyme is active. Expand
Tamapin, a Venom Peptide from the Indian Red Scorpion (Mesobuthus tamulus) That Targets Small Conductance Ca2+-activated K+ Channels and Afterhyperpolarization Currents in Central Neurons*
A new scorpion toxin (tamapin) is identified that binds to SK channels with high affinity and inhibits SK channel-mediated currents in pyramidal neurons of the hippocampus as well as in cell lines expressing distinct SK channel subunits. Expand
