Structural and functional properties of SARS-CoV-2 spike protein: potential antivirus drug development for COVID-19

open access: yesActa Pharmacologica Sinica, 2020
Coronavirus disease 2019 is a newly emerging infectious disease currently spreading across the world. It is caused by a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

A single mutation in the envelope protein modulates flavivirus antigenicity, stability, and pathogenesis [PDF]

open access: yes, 2017
The structural flexibility or 'breathing' of the envelope (E) protein of flaviviruses allows virions to sample an ensemble of conformations at equilibrium.

Antibody Epitopes of Pneumovirus Fusion Proteins [PDF]

open access: yesFrontiers in Immunology, 2019
The pneumoviruses respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) are two widespread human pathogens that can cause severe disease in the young, the elderly, and the immunocompromised. Despite the discovery of RSV over 60 years ago, and hMPV nearly 20 years ago, there are no approved vaccines for either virus.

Brucella NyxA and NyxB dimerization enhances effector function during infection

open access: yesFEBS Letters, Volume 599, Issue 13, Page 1852-1863, July 2025.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...

VAMP721 conformations unmask an extended motif for K+ channel binding and gating control [PDF]

open access: yes, 2016
Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play a major role in membrane fusion and contribute to cell expansion, signaling, and polar growth in plants.

Protein–protein interactions in intracellular membrane fusion

open access: yesCurrent Opinion in Structural Biology, 2000
The fusion of intracellular vesicles with their target membranes is an essential feature of the compartmental structure of eukaryotic cells. This process requires proteins that dictate the targeting of a vesicle to the correct cellular location, mediate bilayer fusion and, in some systems, regulate the precise time at which fusion occurs.

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

open access: yesFEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Oral Immunization With a Plant HSP90-SAG1 Fusion Protein Produced in Tobacco Elicits Strong Immune Responses and Reduces Cyst Number and Clinical Signs of Toxoplasmosis in Mice

open access: yesFrontiers in Plant Science, 2021
Plant 90kDa heat shock protein (HSP90) is a potent adjuvant that increases both humoral and cellular immune responses to diverse proteins and peptides.

Human Cytomegalovirus (HCMV) Glycoprotein gB Promotes Virus Entry In Trans Acting as the Viral Fusion Protein Rather than as a Receptor-Binding Protein

open access: yesmBio, 2013
Human cytomegalovirus (HCMV) glycoproteins gB and gH/gL are both necessary and sufficient for cell-cell fusion. However, it is not clear what roles these glycoproteins play in virus entry, whether acting directly in membrane fusion or in binding ...
