Improved access to SARS-CoV-2 data

NCBI Datasets has a simple, new way to get Coronoviridae data, including from SARS-CoV-2 (Figure 1). The data package includes genomic, protein and CDS sequences, annotation and a comprehensive data report for all complete genomes. You can also target your search to major taxonomic ranks within Coronaviridae.

Interested in a specific protein? The SARS-CoV-2 protein page allows you to choose a protein and download the corresponding sequences, annotation and representative structures from all annotated genomes (Figure 2).

Looking for programmatic access? NCBI Datasets offers the same Coronoviridae genomic data and SARS-CoV-2 protein data through a command-line tool and a RESTful API. These tools support additional filtering including the ability to download only those genomes released after a date you specify.

New GenBank submission options for SARS-CoV-2 submitters

NCBI is pleased to announce ongoing enhancements to submission of SARS-CoV-2 assembled genomes to GenBank, including a streamlined workflow on the web and a new API option. Both new options mean that you can receive accessions for SARS-CoV-2 data submissions more quickly!

A streamlined workflow with improved interface and enhanced validation on both web and API saves you time and effort and, most importantly, makes it possible to get SARS-CoV-2 accession numbers and public release of data within hours. In addition, we automatically annotate all SARS-CoV-2 genomes to produce standardized, consistent annotation which saves you time and benefits researchers who find your data valuable.

New viral protein domain models for annotation of coronaviruses

NLM’s Conserved Domain Database (CDD) has expanded its scope to now include 153 new viral protein domain family models for the annotation of coronaviruses, including models such as for the S1 subunit of coronavirus Spike proteins (cd21527), the nucleocapsid (N) protein of coronavirus (cd21595), and the coronavirus RNA-dependent RNA polymerase (cd21530).

Each curated domain model consists of a multiple sequence alignment containing conserved sequence features that may have been confirmed experimentally, plus links to relevant publications. When available, the domain models include 3D structures with links to interactive 3D views and interacting partners.

Check out this tabular summary of SARS-CoV-2 gene products for links to matching conserved domain models and representative 3D protein structures.

Want to view these alignments in 3D space? We’ve updated iCn3D, a web-based 3D structure viewer, with new rendering, annotation, and alignment features.  Read more about how you can use iCn3D to view and analyze SARS-CoV-2-related structures.

Don’t forget to review our SARS-CoV-2 resources page to keep up to date on other coronavirus data at NCBI!

New NCBI SARS-CoV-2 Resources Page

Are you trying to keep up with the rapidly growing number of biological resources associated with the SARS-CoV-2 virus and the related disease, COVID-19? There’s a new page to help you find SARS-CoV-2-related content available at NCBI (Figure1). This new site will help bench scientists, bioinformaticians, clinicians, and others connect with the information they need to study SARS-CoV-2 and end the COVID-19 pandemic.Cov-2_BLOGFigure 1. The new SARS-CoV-2 resources page providing access to data submissions, literature, molecular information, and clinical resources.

Quickly and easily add your SARS-CoV-2 sequence data to the growing public archive with new, special features and support from NCBI. Our new SARS-CoV-2 sequence submission landing page will help you get started. GenBank submissions are accessioned and released in approximately 1-2 working days, and Sequence Read Archive (SRA) submissions typically processed and released within hours. Submission is simple!

CORD-19: A New Machine Readable COVID-19 Literature Dataset

Are you interested in mining literature about COVID-19 and the novel SARS-Cov-2 virus? You may want to check out the COVID-19 Open Research Dataset (CORD-19). CORD-19 is a collection of more than 13,000 full text articles that focus on COVID-19 and coronaviruses and that were assembled from PMC, the WHO, bioRxiv, and medRxiv. To produce this dataset, the National Library of Medicine partnered with colleagues from the Allen Institute for AI, the Chan Zuckerberg Initiative (CZI), Georgetown University’s Center for Security and Emerging Technology (CSET), Kaggle, Microsoft, and the White House Office of Science and Technology Policy (OSTP).

CORD-19 is available from the Allen Institute and will be updated weekly as new articles become available. The article data are formatted in JSON, making the collection ideal for computational methods such as data mining, machine learning, and natural language processing. We hope this collection serves as a call to action for the community to improve our understanding of coronaviruses and the human diseases they cause. Have a look and let us know what you think!

Rapid access to SARS-CoV-2 data from the current public health emergency

As the global health emergency around the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, formerly 2019-nCoV) continues, we continue to play a key role in providing the biomedical community free and easy access to genome sequences from the coronavirus. You can quickly access these data through the NCBI search (Figure 1).sar-2_sensorFigure 1.  NCBI search results for the term “SARS-COV-2” showing the schematic map of the viral assembly and annotation and buttons that link to the data in the NCBI Virus resource, a specialized BLAST page that searches Betacoronavirus sequences, and the reference assembly download. The bottom panel provides links to the CDC website for COVID-19 information and a link to GenBank®/SRA sequence data.

Novel coronavirus complete genome from the Wuhan outbreak now available in GenBank


Get rapid access to Wuhan coronavirus (2019-nCoV) sequence data from the current outbreak as it becomes available. We will continue to update the page with newly released data.

The complete annotated genome sequence of the novel coronavirus associated with the outbreak of pneumonia in Wuhan, China is now available from GenBank for free and easy access by the global biomedical community. Figure 1 shows the relationship of the Wuhan virus to selected coronaviruses.


Figure 1.  Phylogenetic tree showing the relationship of Wuhan-Hu-1 (circled in red) to selected coronaviruses. Nucleotide alignment was done with MUSCLE 3.8. The phylogenetic tree was estimated with MrBayes 3.2.6 with parameters for GTR+g+i.  The scale bar indicates estimated substitutions per site, and all branch support values are 99.3% or higher.
