Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a positive-sense, single-stranded RNA coronavirus. The virus is the causative agent of coronavirus disease 2019 (COVID-19) and is contagious through human-to-human transmission.

"Severe acute respiratory syndrome coronavirus 2", Wikipedia: The Free Encyclopedia

We modelled the full SARS-CoV-2 proteome based on the NCBI reference sequence NC_045512 which is identical to GenBank entry MN908947, and annotations from UniProt. The underlying SWISS-MODEL workspace projects are accessible below. Our colleagues at the Swiss Institute of Bioinformatics provide more resources on the SARS-CoV-2 genome on ViralZone or allow to track the current outbreak on Nextstrain. Several SARS-CoV-2 proteins reportedly interact in hetero-oligomeric complexes for which we also provide models in a dedicated hetero section. But be aware: the result of any theoretical modelling procedure is NON-EXPERIMENTAL and must be considered with care as models may contain significant errors. To this end SWISS-MODEL provides quality metrics which are described in the help section. The provided modelling projects are based on SWISS-MODEL template library version 2021-01-13 and will be updated as new templates become available.

IntAct lists interactions derived from literature curation or direct user submissions. We extracted those interactions and list the ones between SARS-CoV-2 and human host proteins with their structural coverage in a dedicated interaction page.

Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein.

We model the mature proteins resulting from the cleavage and list them below.

Host translation inhibitor nsp1

Inhibits host translation by interacting with the 40S ribosomal subunit (PubMed:32680882). Nsp1 C terminus binds to and obstructs ribosomal mRNA entry tunnel (PubMed:32680882). Thereby inhibits antiviral response triggered by innate immunity or interferons (PubMed:32680882). The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation (By similarity). Viral mRNAs are not susceptible to nsp1-mediated endonucleolytic RNA cleavage thanks to the presence of a 5'-end leader sequence and are therefore protected from degradation (By similarity). By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (By similarity).

Experimental structures (PDB: 7k3n, 7k7p) are available. Experimental structures of hetero-oligomeric complexes (PDB: 6zlw, 6zm7, 6zme, 6zmi, 6zmo, 6zmt, 6zn5, 6zoj, 6zok, 6zon, 6zp4, 7jqb, 7jqc, 7k5i) exist and high quality models can be extracted from them but should be used with care.

High quality models are available.

Non-structural protein 2 (nsp2)

May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2. Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses.

Only remote homologues were identified as potential template structures, no models have been built.

See here for template search results.

Non-structural protein 3 (nsp3)

Responsible for the cleavages located at the N-terminus of the replicase polyprotein. Participates together with nsp4 in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication (By similarity). Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF3 (PubMed:32733001). Prevents also host NF-kappa-B signaling (By similarity). In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:32726803). Cleaves preferentially ISG15 from substrates in vitro (PubMed:32726803). Can play a role in host ADP-ribosylation by binding ADP-ribose (PubMed:32578982).

Spike glycoprotein (S glycoprotein)

Spike glycoprotein (13-1273): May down-regulate host tetherin (BST2) by lysosomal degradation, thereby counteracting its antiviral activity. Spike protein S1 (13-685): attaches the virion to the cell membrane by interacting with host receptor, initiating the infection. Binding to human ACE2 receptor and internalization of the virus into the endosomes of the host cell induces conformational changes in the Spike glycoprotein (PubMed:32142651, PubMed:32075877, PubMed:32155444). The stalk domain of S contains three hinges, giving the head unexpected orientational freedom (PubMed:32817270). Uses human TMPRSS2 for priming in human lung cells which is an essential step for viral entry (PubMed:32142651). Can be alternatively processed by host furin (PubMed:32362314). Proteolysis by cathepsin CTSL may unmask the fusion peptide of S2 and activate membranes fusion within endosomes. Spike protein S2 (686-1273): mediates fusion of the virion and cellular membranes by acting as a class I viral fusion protein. Under the current model, the protein has at least three conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes. Spike protein S2' (816-1273): Acts as a viral fusion peptide which is unmasked following S2 cleavage occurring upon virus endocytosis.

ORF6 protein (ORF6)

Disrupts cell nuclear import complex formation by tethering karyopherin alpha 2 and karyopherin beta 1 to the membrane. Retention of import factors at the ER/Golgi membrane leads to a loss of transport into the nucleus. Thereby prevents STAT1 nuclear translocation in response to interferon signaling, thus blocking the expression of interferon stimulated genes (ISGs) that display multiple antiviral activities.

Only remote homologues were identified as potential template structures, no models have been built.

Structural Analysis of Mutations

We downloaded SARS-CoV-2 mutation data from GISAID (September 30, 2020) and computed the frequencies of every observed mutation. We summarized the number of different mutations observed at each residue position and summed the frequencies for each residue. For insertions and deletions the frequencies were assigned to the previous residue, except for N-terminal insertions which were assigned to the first residue of the protein.

We performed proximity searches within an 8A radius, and summed both frequencies and number of mutations (excluding the residue itself). To normalize the mutations we first computed the residue-level average of frequencies and number of mutations for each UniProt protein. We then subtracted this baseline value from each residue in the proximity that was mapped to a SARS-CoV-2 protein by SIFTS.
