The proximal origin of SARS-CoV-2
To the Editor — Since the first reports of novel pneumonia (COVID-19) in Wuhan, Hubei province, China1,2, there has been considerable discussion on the origin of the causative virus, SARS-CoV-23 (also referred to as HCoV-19)4. Infections with SARS-CoV-2 are now widespread, and as of 11 March 2020, 121,564 cases have been confirmed in more than 110 countries, with 4,373 deaths5.
SARS-CoV-2 is the seventh coronavirus known to infect humans; SARS-CoV, MERS-CoV and SARS-CoV-2 can cause severe disease, whereas HKU1, NL63, OC43 and 229E are associated with mild symptoms6. Here we review what can be deduced about the origin of SARS-CoV-2 from comparative analysis of genomic data. We offer a perspective on the notable features of the SARS-CoV-2 genome and discuss scenarios by which they could have arisen. Our analyses clearly show that SARS-CoV-2 is not a laboratory construct or a purposefully manipulated virus.
Notable features of the SARS-CoV-2 genome
Our comparison of alpha- and betacoronaviruses identifies two notable genomic features of SARS-CoV-2: (i) on the basis of structural studies7,8,9 and biochemical experiments1,9,10, SARS-CoV-2 appears to be optimized for binding to the human receptor ACE2; and (ii) the spike protein of SARS-CoV-2 has a functional polybasic (furin) cleavage site at the S1–S2 boundary through the insertion of 12 nucleotides8, which additionally led to the predicted acquisition of three O-linked glycans around the site.
1. Mutations in the receptor-binding domain of SARS-CoV-2
The receptor-binding domain (RBD) in the spike protein is the most variable part of the coronavirus genome1,2. Six RBD amino acids have been shown to be critical for binding to ACE2 receptors and for determining the host range of SARS-CoV-like viruses7. With coordinates based on SARS-CoV, they are Y442, L472, N479, D480, T487 and Y4911, which correspond to L455, F486, Q493, S494, N501 and Y505 in SARS-CoV-27. Five of these six residues differ between SARS-CoV-2 and SARS-CoV (Fig. 1a). On the basis of structural studies7,8,9 and biochemical experiments1,9,10, SARS-CoV-2 seems to have an RBD that binds with high affinity to ACE2 from humans, ferrets, cats and other species with high receptor homology7.

The spike protein of SARS-CoV-2 (red bar at top) was aligned against the most closely related SARS-CoV-like coronaviruses and SARS-CoV itself. Key residues in the spike protein that make contact to the ACE2 receptor are marked with blue boxes in both SARS-CoV-2 and related viruses, including SARS-CoV (Urbani strain). b, Acquisition of polybasic cleavage site and O-linked glycans. Both the polybasic cleavage site and the three adjacent predicted O-linked glycans are unique to SARS-CoV-2 and were not previously seen in lineage B betacoronaviruses. Sequences shown are from NCBI GenBank, accession codes MN908947, MN996532, AY278741, KY417146 and MK211376. The pangolin coronavirus sequences are a consensus generated from SRR10168377 and SRR10168378 (NCBI BioProject PRJNA573298)29,30.

While the analyses above suggest that SARS-CoV-2 may bind human ACE2 with high affinity, computational analyses predict that the interaction is not ideal7 and that the RBD sequence is different from those shown in SARS-CoV to be optimal for receptor binding7,11. Thus, the high-affinity binding of the SARS-CoV-2 spike protein to human ACE2 is most likely the result of natural selection on a human or human-like ACE2 that permits another optimal binding solution to arise. This is strong evidence that SARS-CoV-2 is not the product of purposeful manipulation.

Thank you - mm - a valid post of a different scientist reaching a different opinion on the origin of the wuhan virus. It is different than the above quoted article by Yan, et al, as to lab or spontaneous origins. Bear in mind that viral selection without genetic manipulation (CRISPR inserts, for example) could also give rise to wuhan virus in a laboratory.
As Yan wrote - further research is needed - and in a non-politicized environment - as the DPST's are exposing their TDS and willingness to defend China , its' behavior regarding the release of the virus and initial pandemic response, in an effort to discredit the POTUS.
Very much as the NYCrimes closed the subject of 'climate change' to debate as to human causation, and the efficacy of the proposed Soylent Green New Deal to change the perceived issue without any cooperation from the rest of the world .
Narrative should not eclipse Science - nor bend science to pre-determined political/narrative outcomes. As seen in marxist dominated counties.
I applaud the thrust for further research in open forums without political pre-determination of research outcomes.

Oeb take a cold shower.You all wound up.
The OP called it Zenote not me.
I am not a molecular biologist but I most definitely am part of the scientific community and also mostly the medical community.
I have made a pledge on here to not make attacks personal.Also to not question peoples intellect or education or lack thereof.
I too had an academic career and an even longer career in direct patient care which I still have.
I am for all scientific inquiry and research and would not stand in the way of advancing any of it.I was not saying that those journals were the "Only" journals.I was just pointing out that generally valid,vetted,and reviewed research will eventually find it's way to a conventional journal such as those named.And an assertion such as this lady is making would be a huge deal.
I was just pointing out that which you affirmed,that things posted on Zenodo have not been reviewed such as material in those journals would be.They may have merit.Time will tell.
If you disagree with the politics of my posts,fine,but please don't call me ignorant or demean me as to be of lesser status than yourself.
Actually this whole discussion is moot now cause Trump in his own voice has acknowledged that he knew all about the severity of the virus early and how it arose, whether from nature or a lab is not pertinent.What is pertinent is his lying to the people regarding it.And his inadequate response to it.
Certainly if this were to be a "Weaponized" virus intentionally created and released by China then their part would be bad but in another way it would still come down to Trump's response to it.
