0-56 |
Sentence |
denotes |
Coronavirus genomes and subgenomes encode six ORFs (31). |
| T88 |
57-131 |
Sentence |
denotes |
The majority of the 5′ end is occupied by ORF1a/b, which produces 16 nsps. |
| T89 |
132-254 |
Sentence |
denotes |
The two polyproteins, pp1a and pp1ab, are initially produced from ORF1a/b by a −1 frameshift between ORF1a and ORF1b (32). |
| T90 |
255-423 |
Sentence |
denotes |
The virus-encoded proteases cleave polyproteins into individual nsps (main protease [Mpro], chymotrypsin-like protease [3CLpro], and papain-like proteases [PLPs]) (42). |
| T91 |
424-515 |
Sentence |
denotes |
SARS-CoV-2 also encodes these nsps, and their functions have been elucidated recently (31). |
| T92 |
516-745 |
Sentence |
denotes |
Remarkably, a difference between SARS-CoV-2 and other CoVs is the identification of a novel short putative protein within the ORF3 band, a secreted protein with an alpha helix and beta-sheet with six strands encoded by ORF8 (31). |
