Product: orf1ab polyprotein (pp1ab)
It was assumed that the SARS orf1ab polyprotein processing map should be similar to that of murine hepatitis virus; however, of the two MHV papain-like proteinases, only PL2-PRO is well conserved for SARS coronavirus. The mature peptides located downstream from nsp4-pp1a/pp1ab are cleaved from the polyprotein by the nsp5-pp1a/pp1ab proteinase 3CL-PRO. The orf1a/orf1b translational frameshift, the predicted processing map, and both proteinase activities have been supported by in vitro expression and mutagenesis experiments (Thiel et al., 2003); -1 frameshift
