Comparison of natural HCoV-229E diversity to cell entry effects in the RBD binding loops.

We compared the natural amino-acid variation of HCoV-229E spike to the measured effects of mutations on cell entry in the RBD binding loops. For further exploration:

Site-wise Amino Acid Diversity of Natural Sequences of HCoV-229E

  • The black bars represent the effective number of amino acids at each site, calculated from Shannon entropy.
  • The bar at the top indicate major spike domains: NTD, RBD, and S2.
  • The loop labels (L1, L2, L3) mark the three receptor-binding loops within the RBD.
  • Hover over bars to see the exact effective number of amino acids, amino acid richness, and domain assignment for each site.

RBD binding loops cell entry effcets

  • The three panels show Loop 1 (308-325), Loop 2 (352-359), and Loop 3 (404-408) side by side for easy comparison.
  • The X marks indicate the 1984 strain amino acid identity at each position.
  • Hover over any cell to see the exact site, wildtype amino acid, mutant amino acid, and quantitative cell entry effect.
