Purpose
The purpose of this research is to determine how and why a mutation at the 501 position of the spike protein of Covid 19 results in a higher binding affinity to the human ACE2 receptor.
Methods and results
Part 1: Download SARS-CoV-2 Surface Glycoprotein Viral Sequences
- Navigated to NCBI Virus to collect surface glycoprotein viral sequences of SARS-CoV-2
- Selected sequences based on geographic regions
- Clicked on 'geographic region' on the left side of the page
- Typed in United Kingdom, Spain, Iran, Saudi Arabia, Italy, Venezuela, Peru, and Brazil, and selected two sequences from each country
- Clicked on 'download' and then checked 'nucleotide' under 'sequence data (FASTA format) and downloaded all of the sequences in FASTA format

- Determined the nucleotide at the 501 position by using word count on google docs
- For each sequence, I deleted the amount of characters until I reached 501, and determined the nucleotide at that position. Here are the results:
- 1st UK strain position 501: N (asparagine)
- 2nd UK strain position 501: N (asparagine)
- 1st Spain strain position 501: N (asparagine)
- 2nd Spain strain position 501: N (asparagine)
- 1st Iran strain position 501: N (asparagine)
- 2nd Iran strain position 501: N (asparagine)
- 1st Saudi Arabia strain position 501: N (asparagine)
- 2nd Saudi Arabia strain position 501: Q (glutamine)
- 1st Venezuela strain position 501: N (asparagine)
- 2nd Venezuela strain position 501: N (asparagine)
- 1st Peru strain position 501: Insufficient number of residues
- 2nd Peru strain position 501: Insufficient number of residues
- 1st Brazil strain position 501: N (asparagine)
- 2nd Brazil strain position501: N (asparagine)
- For each sequence, I deleted the amount of characters until I reached 501, and determined the nucleotide at that position. Here are the results:
Part 2: Creating a Phylogenetic Tree and Sequence Alignment
- I went to [http://www.phylogeny.fr/simple_phylogeny.cgi?workflow_id=f6c1c87f6ac1d379903543866e4da087&tab_index=3%7C to create a phylogenetic tree and sequence alignment
- I scrolled down to section labeled 'phylogeny analysis' and clicked on 'one text'
- I clicked in the large text field labeled ‘Upload your set of sequences in FASTA, EMBL, or NEXUS format,’ copied and pasted the list of sequences, and clicked 'submit'
- Once alignment was completed, I saw a page with Alignment results, a page with phylogeny results, and a page with Tree rendering results.
- I clicked on 'tree rendering,' the tree is shown below:
- I found the numbered tabs located below the text One Click Mode, and clicked the tab labeled 3.Alignment.
- Towards the bottom of the page, I clicked Alignment in Clustal format under Outputs. This displayed the alignment in text-only format, where conservation is displayed as a symbol underneath the alignment block as such:
- “*” for invariant
- “:” for highly conserved
- “.” for weakly conserved
- "space" for not conserved
- This entire alignment is here:
Went to [Structure Database] and Used the Web-Based iCn3D Viewer
- Analyzed position 501 using iCn3D viewer by searching for SARS-CoV-2 RBD
- Once data loaded, I clicked on 'details' and highlighted position 501-asparagine

Scientific Conclusion
This research project involved finding sequences from various countries including: UK, Spain, Italy, Iran, Saudi Arabia, Venezuela, Peru, and Brazil, to see if a mutation at position 501 could be found in any of them. This mutation was of particular interest, as studies have shown that it leads to greater binding affinity. Although no sequences were found to have this particular mutation, research has shown that a change at this particular residue position would have adversarial effects, as the asparagine that is normally present at 501 provides an overall structural stability to the RBD of the spike protein. Furthermore, it promotes the network of hydrophilic interactions. If say, a hydrophobic amino acid took its place, then that would greatly alter the stability of the RBD structure, and could facilitate a higher binding affinity to human ACE2.
