RCSB PDB is a central resource in the global fight against SARS-CoV-2, the agent of the COVID-19 pandemic. The PDB is the primary repository of atomic structures of viral proteins and nucleic acids, providing the basic understanding that will be needed to discover new therapies and develop vaccines. RCSB PDB provides many resources to access and analyze these structures, and general resources to help understand the mechanisms of the viral life cycle and how they impact health.
A series of articles provides an introduction to how the biological macromolecules in the PDB are driving research and discovery related to SARS-CoV-2. A new feature article, Passive Immunization with Convalescent Antibodies, describes how purified antibodies may be used to treat infection by coronavirus.
The painting SARS-CoV-2 and Neutralizing Antibodies by David S. Goodsell shows a cross section through SARS-CoV-2 surrounded by blood plasma, with neutralizing antibodies in bright yellow. It was commissioned for the cover of a special COVID-19 issue of Nature.
Respiratory Droplet shows a cross section through a small respiratory droplet, like the ones that are thought to transmit SARS-CoV-2. The virus is shown in magenta, and the droplet is also filled with molecules that are present in the respiratory tract.
Goodsell's molecular landscapes are available from PDB-101 in a special SciArt Digital Archive. These watercolor paintings integrate information from structural biology, microscopy and biophysics to simulate detailed views of the molecular structure of living cells.

Many thanks to Steven Leard (ISMB) for his continued support. This year's prize was judged by RCSB PDB's Stephen K. Burley and Sebastian Bittrich.
At this year's American Crystallographic Association's Annual Meeting, the RCSB PDB Poster Prize award went to Takahiro Yamauchi for
Crystal and Solution structures of Proliferating Cell Nuclear Antigen from Crenarchaeon Aeropyrum pernix Takahiro Yamauchi (Iryo Sosei University and Fukushima Rosai Hospital, Japan), Tsubasa Takemori, Makiko Kikuchi, Yasuhito Iizuka, Satoshi Ishikawa, and Masaru Tsunoda (Iryo Sosei University)
The judges also awarded an Honorable Mention to Ravi Yadav (Purdue University) for
Structural basis of Neisserial lactoferrin binding protein B function Ravi Yadav (Purdue University), Srinivas Chakravarthy (Argonne National Laboratory), Courtney Daczkowski (Purdue University), Nicholas Noinaj (Purdue University)
An intensive online learning experience hosted by RCSB PDB and the Rutgers University Institute for Quantitative Biomedicine introduced students to Structural Bioinformatics by focusing on the main protease structure of SARS-CoV-2.
At the end, the student researchers understood how the protein evolved during the first six months of the COVID-19 pandemic by exploring amino acid sequence and 3D atomic-level structure.

Boot Camp graduate Sophia Staggers (Frostburg State University) presented her poster Understanding the evolution of SARS-CoV-2 non-structural protein 15 (Nsp15) in 3D at the 2020 American Crystallographic Association virtual meeting and was recognized with the 2020 MiTeGen-Society of Physics Students Undergraduate Poster Prize.
Sophia originally planned to spend her summer with the RCSB PDB team at Rutgers University as part of the Research Intensive Summer Experience (RISE) at Rutgers program. Over the course of the five weeks after the Boot Camp, Sophia and other students used their training to study the other proteins in the coronavirus.
The RCSB PDB will be a part of this year’s STEM Teachers Expo. This year’s Expo will be held October 23-25, 2020 via Zoom. The Expo supports educators is their professional development delivering a diverse program exposing new ideas and developments in STEM education.
RCSB PDB teamed up with Biochemistry Literacy for Kids and Schrödinger to present a session on Strengthening virtual Chemistry and Biology Instruction Through 3D Modeling. The presentation will be a part of GENERAL STEM Block D on Saturday, October 24 at 5:45-7:15 PM EDT.
This image of RNA Polymerase by RCSB PDB's Maria Voigt was selected as a national finalist in the 2019 Wiki Science Competition in the United States. The jury selected 36 finalists across six categories from 1,144 submissions.
RNA polymerase (purple) is a complex enzyme at the heart of transcription. During this process, the enzyme unwinds the DNA double helix and uses one strand (darker orange) as a template to create the single-stranded messenger RNA (green), later used by ribosomes for protein synthesis. From the RNA polymerase II elongation complex of Saccharomyces cerevisiae (PDB Structure 1i6h) as seen in PDB-101's What is a Protein?.
This image, one of PDB-101's award-winning creations, is available for download as part of the Poster Collection.
