Detection, sequencing and annotation
★ PriSeT | Efficient De Novo Primer Discovery

Appropriate PCR primer pairs for DNA metabarcoding would match to a broad evolutionary range of taxa, such that we only need a few to achieve high taxonomic coverage. At the same time, the DNA barcodes between primer pairs should be different to allow us to distinguish between species to improve resolution. PriSeT finds a primer set P balancing both: high taxonomic coverage and high resolution. It is capable of processing large libraries and is robust against mislabeled or low quality references. It tackles the computationally expensive steps with linear runtime filters and efficient encodings.

PriSeT has been applied to 19 SARS-CoV-2 genomes and computed 114 new primer pairs with the additional constraint that the sequences have no co-occurrences in other taxa. These primer sets would be suitable for empirical testing.

VADR | validation and annotation of virus sequence submissions to GenBank

VADR (Viral Annotation DefineR) validates and annotates viral sequences in GenBank submissions. The annotation system is based on the analysis of the input nucleotide sequence using models built from curated RefSeqs. Hidden Markov models are used to classify sequences by determining the RefSeq they are most similar to, and feature annotation from the RefSeq is mapped based on a nucleotide alignment of the full sequence to a covariance model. Predicted proteins encoded by the sequence are validated with nucleotide-to-protein alignments using BLAST.

We considered 313 HIV-infected individuals for whom reliable estimates of infection dates and next-generation sequencing (NGS)-derived nucleotide frequency data were available. Fraction of ambiguous nucleotides (FAN) obtained by population sequencing were available for 207 samples. We assessed whether average pairwise diversity (APD) calculated using NGS sequences provided a more exact prediction of TSI and classification of infection recency (<1 year post-infection) compared to FAN. NGS-derived APD classifies an infection as recent with a sensitivity of 88% and specificity of 85%. When considering only the 207 samples for which FAN were available, NGS-derived APD exhibited a higher sensitivity (90% vs 78%) and specificity (95% vs 67%) than FAN. Additionally, APD can estimate TSI with a mean absolute error of 0.84 years, compared to 1.03 years for FAN.},

★ Rfam COVID-19 Resources

In response to the SARS-CoV-2 outbreak, Rfam produced a special release 14.2 that includes 10 new and 4 revised families that can be used to annotate the SARS-CoV-2 and other Coronavirus genomes with RNA families.

RNACentral Betacoronavirus sequence similarity search

RNAcentral has launched a new tool to help scientists studying Coronaviruses to search thousands of viral genomes and explore results by virus, host, country, and more. The new search uses nhmmer and enables the users to explore the results using facets powered by the EBI Search. For example, it is possible to search for a fragment of a SARS-CoV-2 genome, select similar sequences identified in COVID-19 patients, and browse sequence variants from different countries.

The viral sequences are regularly extracted from the NCBI BLAST database and the metadata is retrieved from the associated INSDC entries. While the search uses the same sequences as NCBI BLAST, there are several important differences:

  • Support for facets and keyword searches for exploring results
  • Use nhmmer as the search engine
  • Explore up to 1,000 top hits (compared to 100 in BLAST)
  • Integration with Rfam to annotate structured RNA elements

The search is produced and maintained by the RNAcentral team, repurposing the infrastructure of the RNAcentral sequence similarity search to query betacoronavirus sequences instead of non-coding RNAs.

Protein annotation
Pfam protein families database

The Pfam protein families database is widely used in the field of molecular biology for large-scale functional annotation of proteins. The latest release of Pfam, version 33.1, contains an updated set of models that comprehensively cover the proteins encoded by SARS-CoV-2. The Pfam profile hidden Markov model (HMM) library in combination with the HMMER software facilitates rapid search and annotation of coronaviruses and can be used to generate multiple sequence alignments that allow the identification of mutations and clusters of related sequences, particularly useful for outbreak tracking and studying the evolution of Coronaviruses.

UniProt COVID-19 protein portal | rapid access to protein information

COVID-19 UniProt portal provides early pre-release access to (i) SARS-CoV-2 annotated protein sequences, (ii) closest SARS proteins from SARS 2003, (iii) human proteins relevant to the biology of viral infection, like receptors and enzymes, (iv) ProtVista visualisation of sequence features for each protein, (v) links to sequence analysis tools, (vi) access to collated community-contributed publications relevant to COVID-19, as well as (vii) links to relevant resources.

The COVID-19 portal enables community crowdsourcing of publications via the “Add a publication” feature within any entry. Thus, the community can assist in associating new or missing publications to relevant UniProt entries. ORCID is used as a mechanism to validate user credentials as well as recognition for contribution. Ten publication submissions have been received so far, contributing to our understanding of the virus biology. The COVID-19 UniProt portal advances SARS-CoV-2 research by providing the latest knowledge on proteins relevant to the disease for both the virus and human host.

UniProt also hosted webinars to describe the portal and publication submission system.

ELM and IUPred2A | Detection of functional regions in disordered proteins

The ELM resource offers a collection of short linear motifs that mediate interactions crucial in both native cell regulation and pathogenic interference. The latest 2020 release of ELM includes updated motif definitions and new instances covering nearly 300 motif classes based on over 3,400 publications. The ELM server includes an online tool for the identification of motifs in user input sequences, using context filters (based on structural information, localization, sequence complexity and conservation) to refine results. The opening page has been updated to give references to an overview of motif hijacking in viruses in general, and an application to detecting SARS-CoV-2 motif usage in host cell attachment and modulation.

The IUPred2A server is a biophysics-based prediction to identify intrinsically disordered protein regions (IDRs) and binding sites inside IDRs. This can capture longer and more specialized disordered interaction regions complementing linear motifs captured by ELM. Both ELM and IUPred2A identify functional regions that are disordered and generally less conserved due to rapid evolvability, and hence their outputs complement the well conserved functional regions identified by Pfam. ELM and IUPred2A mutually include each other’s predictions, and both methods utilize the newest data from UniProt and Pfam. This way users can get a fully annotated report on candidate disordered interaction sites, highlighting their relationships with Pfam domains, for any protein of interest.

★ CoV-GLUE | Amino acid analysis for the SARS-CoV-2 pandemic

SARS-CoV-2 will naturally accumulate nucleotide mutations in its RNA genome as the pandemic progresses. On average the observed changes would be expected to have no or minimal consequence on virus biology. However, tracking these changes will help us better understand the virus pandemic.

CoV-GLUE is an online web application for the interpretation and analysis of SARS-CoV-2 virus genome sequences, with a focus on amino acid sequence variation. It is based on the GLUE data-centric bioinformatics environment and provides a browsable database of amino acid replacements and coding region indels that have been observed in sequences from the pandemic. Users may also analyse their own SARS-CoV-2 sequences by submitting them to the web application to receive an interactive report containing visualisations of phylogenetic classification and highlighting genomic variation of potentially high impact, for example, linked to primer mismatches.

In-host dynamics
COVID19 tissue simulator | Prototype 2-D multicellular simulation of COVID19
COVID19 tissue simulator simulates replication dynamics of SARS-CoV-2 in a layer of epithelium. It is being rapidly prototyped and refined with community support.

In this model, SARS-CoV-2 infects a single cell, or a solution of virions is administered to the extracellular space. The virus is uncoated to explose viral RNA, which synthesizes viral proteins that are assembled into a virion. Assembled virions are exported to the environment, where they can diffuse and infect other cells. In the extracellular space, virions adhere to ACE2 receptors and get internalized through endocytosis. Internalized ACE2 receptors release their virus cargo and are recycled back to the surface.

The model includes a basic pharmacodynamic response (to assembled virions) to cause cell apoptosis. Apoptosed cells release some or all of their internal contents, notably including virions.
