Structural analysis of SARS-CoV-2 Envelope and Membrane proteins reveals high similarity to bat and pangolin coronaviruses. Specific structural differences in SARS-CoV-2 proteins may explain its cross-species transmission and unique viral properties.
Area of Science:
- Virology
- Structural Biology
- Genomics
Background:
- Coronavirus Disease 2019 (COVID-19) is a novel viral infection caused by SARS-CoV-2.
- Genomic data indicates SARS-CoV-2 is related to bat and pangolin coronaviruses.
Purpose of the Study:
- To perform a structural comparison of SARS-CoV-2 Envelope (E) and Membrane (M) proteins.
- To compare these proteins with homologous proteins from related viruses, including bat and pangolin coronaviruses.
Main Methods:
- Comparative structural analysis of E and M proteins.
- Structural modeling to map variant sites onto 3D protein structures.
Main Results:
- SARS-CoV-2 E and M proteins exhibit high structural similarity to those of bat and pangolin coronaviruses.
- Identified specific structural differences in SARS-CoV-2 E and M proteins compared to related viruses.
Conclusions:
- Structural similarities suggest a common evolutionary origin.
- Distinct structural features of SARS-CoV-2 proteins may be linked to its cross-species transmission and pathogenicity.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
