Heroes of hope (Kanika Khanna, Stanford University)

The contest came forth at a time when almost everyone is struggling with the changes accompanying the pandemic. Each of us are grappling with one or another grief and ‘hoping’ for something good to happen. This contest was a way for me to get out of my own grief and create something that would be a source of joy not only for me but may be someone else out there as well. And who better to dedicate this creation to other than our ‘Heroes of hope’, the health care workers at the frontline who are fighting the pandemic day in and day out, without any selfish motives. Putting their lives at risk, away from their families, I can’t even begin to imagine the agony they must be going through.

1. The central figure of the creation is a masked healthcare worker and all the components that make up the worker are molecules in our body that fight viral and bacterial infections, antibodies and components of complement system, namely IgA, IgG, IgM and Complement factors C3, H, C4A and B represented in the face, mask, neck and body of the worker. This is to represent that just as our body uses these molecules to fight an infection, the health care worker is fighting the deadly pandemic for the entire world and he/she may be our ‘antibody’ against the virus, so to say.
2. The mask also has actin which is known to have a rare combination of strength and sensitivity, being used in some of the most demanding structural activities in the body. This also represents the importance of wearing masks in these times not only to protect ourselves from the virus but others around us. I have also put a few ACE2 receptors embedded in the mask to show that these can be ‘buried’ or protected from viral infection with the proper use of face masks.
3. The virus particles shown on the outside have their nucleocapsid proteins arranged in symbol of ‘theta’, which is the Greek symbol of death representing the fatal powers of the virus. I am hoping with this creation, I am able to reach out to a broader audience with two messages. As the title of the creation ‘Heroes of hope’ suggests, we need to thank our healthcare workers big time for the contributions they are making to fight the deadly pandemic. Second, we need to be more vigilant about how we conduct ourselves so that we can keep each other safe during these tough times. Only then can we hope for a better future for the world today!

Enter the Coronavirus CellPAINT Contest by May 31

04/28/2020

Show us how you can illustrate coronavirus with a new version of CellPAINT. The Scripps Research Center for Computational Structural Biology (CCSB) in association with RCSB PDB is hosting an image contest. There are two categories: Science and Art.

Images for the “Science” category need to be accurate and present aspects of coronavirus structure and biology--create something that helps us understand the virus.

In the “Art” category, let your creativity run wild with any topic--create something that amazes and inspires.

CellPAINT

CellPAINT is software for drawing pictures of cellular and viral systems, similar to a traditional digital paint program. The shapes and sizes of molecules are based on atomic structures taken from the Protein Data Bank, and the program allows you to build membranes, add membrane-bound proteins, and fill the inside and outside with soluble proteins and other molecules (more information).

For this contest, you can submit images created using the web-based program or the stand-alone version.

A CellPAINT tutorial provides information on how to create images using the program and a summary of the ultrastructure of the virus.

SARS-CoV2 binds to the receptor protein ACE2 on the surface of cells that it infects. By studying the interaction of the SARS-CoV-2 spike protein (S) to this receptor, researchers hope to design new inhibitors to block infection. Several structures have recently been released that reveal this interaction. 6m17 is the structure of the receptor binding domain (RBD) of SARS-CoV-2 S protein with the ACE2-B^0 AT1 complex, suggesting simultaneous binding of two S protein trimers to an ACE2 dimer. 6m18 and 6m1d are ACE2-B^0 AT1 complex structures in closed and open forms without RBD binding. B^0 AT1 stabilizes full length ACE2 in the structural studies.

New Coronavirus Protease Structure Available

02/04/2020

PDB data provide a starting point for structure-guided drug discovery

A high-resolution crystal structure of COVID-19 (2019-nCoV) coronavirus 3CL hydrolase (Mpro) has been determined by Zihe Rao and Haitao Yang's research team at ShanghaiTech University. Rapid public release of this structure of the main protease of the virus (PDB 6lu7) will enable research on this newly-recognized human pathogen.

Recent emergence of the COVID-19 coronavirus has resulted in a WHO-declared public health emergency of international concern. Research efforts around the world are working towards establishing a greater understanding of this particular virus and developing treatments and vaccines to prevent further spread.

https://doi.org/10.2210/pdb6lu7/pdb

While PDB entry 6lu7 is currently the only public-domain 3D structure from this specific coronavirus, the PDB contains structures of the corresponding enzyme from other coronaviruses. The 2003 outbreak of the closely-related Severe Acute Respiratory Syndrome-related coronavirus (SARS) led to the first 3D structures, and today there are more than 200 PDB structures of SARS proteins. Structural information from these related proteins could be vital in furthering our understanding of coronaviruses and in discovery and development of new treatments and vaccines to contain the current outbreak.

The coronavirus 3CL hydrolase (Mpro) enzyme, also known as the main protease, is essential for proteolytic maturation of the virus. It is thought to be a promising target for discovery of small-molecule drugs that would inhibit cleavage of the viral polyprotein and prevent spread of the infection.

Comparison of the protein sequence of the COVID-19 coronavirus 3CL hydrolase (Mpro) against the PDB archive identified 95 PDB proteins with at least 90% sequence identity. Furthermore, these related protein structures contain approximately 30 distinct small molecule inhibitors, which could guide discovery of new drugs. Of particular significance for drug discovery is the very high amino acid sequence identity (96%) between the COVID-19 coronavirus 3CL hydrolase (Mpro) and the SARS virus main protease (PDB 1q2w). Summary data about these closely-related PDB structures are available (CSV) to help researchers more easily find this information. In addition, the PDB houses 3D structure data for more than 20 unique SARS proteins represented in more than 200 PDB structures, including a second viral protease, the RNA polymerase, the viral spike protein, a viral RNA, and other proteins (CSV).

Public release of the COVID-19 coronavirus 3CL hydrolase (Mpro), at a time when this information can prove most vital and valuable, highlights the importance of open and timely availability of scientific data. The wwPDB strives to ensure that 3D biological structure data remain freely accessible for all, while maintaining as comprehensive and accurate an archive as possible. We hope that this new structure, and those from related viruses, will help researchers and clinicians address the COVID-19 coronavirus global public health emergency.
