Deletion in the C-terminal region of the envelope glycoprotein in some of the Indian SARS-CoV-2 genome.

ABSTRACT: The envelope glycoprotein (E) is the smallest structural component of SARS-CoVs; plays an essential role in the viral replication starting from envelope formation to assembly. The in silico analysis of 2086 whole genome sequences from India performed in this study provides the first observation on the extensive deletion of amino acid residues in the C-terminal region of the envelope glycoprotein in 34 Indian SARS-CoV-2 genomes. These amino acid deletions map to the homopentameric interface and PDZ binding motif (PBM) present in the C-terminal region of E protein as well as immediately after the reverse primer binding region as per Charité protocol in 26 of these genomes, hence, their detection through RT-qPCR may not be hampered and therefore E gene-based RT-qPCR would still detect these i
