Genomic organization of strain Sczy3. The complete genome consists of 27,695 bp single-strand (+) RNA (including poly-A tails). The replicase gene is shown in gray with nonstructural protein domains (nsp) 2–16 indicated. The transcription-regulating sequence (TRS) is located in front of each gene. The PLpro is located in polyprotein G675–G2264 and the C-end cleavage site is AG/GV.Mpro is located in polyprotein A2279–Q3085 and the C-end cleavage site is LQ/SS. RDRP is located on polyprotein S3929–Q4868, and the C-end cleavage site is LQ/SC
