SARS-CoV-2 Replicase Polyprotein 1ab

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** SARS-CoV-2 replicase polyprotein 1ab (7096 aa, ~794 kDa) is encoded by the SARS-CoV-2 ORF1ab gene. This protein is involved in self-proteolysis that yields 15 non-structural viral proteins that replicate and transcribe the viral genome.
