Sequence and structural analysis of COVID-19 E and M proteins with MERS virus E and M proteins-A comparative study.

ABSTRACT: The outbreak of SARS in 2003, MERS in 2012, and now COVID-19 in 2019 has demonstrated that Coronaviruses are capable of causing primary lethal infections in humans, and the pandemic is now a global concern. The COVID-19 belongs to the beta coronavirus family encoding 29 proteins, of which four are structural, the Spike, Membrane, Envelope, and Nucleocapsid proteins. Here we have analyzed and compared the Membrane (M) and Envelope (E) proteins of COVID-19 and MERS with SARS and Bat viruses. The sequence analysis of conserved regions of both E and M proteins revealed that many regions of COVID-19 are similar to Bat and SARS viruses while the MERS virus showed variations. The essential binding motifs found in SARS appeared in COVID-19. Besides, the M protein of COVID-19 showed a distinct seri
