| Modified Residue | |
| Post Translational Modification | PTM: Specific enzymatic cleavages in vivo yield mature proteins. The protease probably cleaves itself and releases the RdRp (Potential). Cleavages have been shown in the P1 protein, but since the N-terminus containing the serine protease is shared between P1 and P1-P2, cleavages should also occur within the P1-P2 protein. {ECO:0000305}. |
