Conserved High Free Energy Sites in Human Coronavirus Spike Glycoprotein Backbones

Journal of Computational Biology, 2020
Methods previously developed by the author are applied to uncover several sites of interest in the spike glycoproteins of all known human coronaviruses (hCoVs), including SARS-CoV-2 that causes COVID-19. The sites comprise three-dimensional neighborhoods of peptides characterized by four key properties: (1) they pinpoint regions of high free energy in ...

The consensus B-cell epitopes of SARS coronavirus spike glycoprotein

, 2020
The goal of this paper is to obtain the consensus B-cell epitopes calculated from the spike glycoprotein of SARS-CoV, after an analysis of 946 epitopes predicted by thirteen different computer programs. To reduce and select the best epitopes, we define a function called $<F>$ that includes energy and structural factors obtained from the changes ...

Structure-guided covalent stabilization of coronavirus spike glycoprotein trimers in the closed conformation

Nature Structural & Molecular Biology, 2020
AbstractSARS-CoV-2 is the causative agent of the COVID-19 pandemic, with 10 million infections and more than 500,000 fatalities by June 2020. To initiate infection, the SARS-CoV-2 spike (S) glycoprotein promotes attachment to the host cell surface and fusion of the viral and host membranes.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

Advanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

LSECtin interacts with filovirus glycoproteins and the spike protein of SARS coronavirus

Virology, 2005
Cellular attachment factors like the C-type lectins DC-SIGN and DC-SIGNR (collectively referred to as DC-SIGN/R) can augment viral infection and might promote viral dissemination in and between hosts. The lectin LSECtin is encoded in the same chromosomal locus as DC-SIGN/R and is coexpressed with DC-SIGNR on sinusoidal endothelial cells in liver and ...

Understanding Viral Transmission Behavior via Protein Intrinsic Disorder Prediction: Coronaviruses [PDF]

, 2012
Besides being a common threat to farm animals and poultry, coronavirus (CoV) was responsible for the human severe acute respiratory syndrome (SARS) epidemic in 2002-4. However, many aspects of CoV behavior, including modes of its transmission, are yet to

Molecular modelling of S1 and S2 subunits of SARS coronavirus spike glycoprotein

Biochemical and Biophysical Research Communications, 2003
The S1 and S2 subunits of the spike glycoprotein of the coronavirus which is responsible for the severe acute respiratory syndrome (SARS) have been modelled, even though the corresponding amino acid sequences were not suitable for tertiary structure predictions with conventional homology and/or threading procedures.
