Catalytic, aminoacylation domain; GST, glutathione S-transferase-like motif; LZ, leucine zipper; tRNA, tRNA binding domain. WebbThe single-chain positive sense RNA of SARS-CoV-2 is used directly as mRNA [ 18 ]. Using this mRNA, ribosomes of the host cells synthesize two large polypeptides, rep1a and rep1a/1b. Then, rep1a and rep1b are proteolytically cleaved into 16 virally-encoded nonstructural proteins (NSPs) [ 33, 34, 35, 36, 37, 38 ].
