Background: 3CL Protease

The 3CL protease (aka 3CLpro, Mpro or "Main" Protease) from the human MERS-CoV coronavirus (Middle East Respiratory Syndrome coronavirus) is a C30-type cysteine protease located within the non-structural protein 3 (NS3) section of the viral polypeptide that cleaves proteins with sequences including a LQ[S/A/G] c-terminal to the glutamine residue.  3CL protease activity is required to process the viral polyprotein into functional, mature subunits, and there are 11 or more sites of cleavage, many containing the sequence LQ[S/A/G]; the protease cleaves c-terminal to the glutamine amino acid.
