Background Information

The new coronavirus SARS-CoV-2 expresses two proteases, the papain-like protease (PLpro) and 3C-like protease (3CLpro). Both belong to the group of cysteine proteases, as they have a cysteine residue at their catalytic site. Their main function is the processing of the viral polyprotein, that contains two cleavage sites to build up the viral replicase complex. Additionally, PLpro has the ability of removing ISG15 and ubiquitin from viral proteins expressed in the cell, this enables evasion from the innate immune response by the host. This presents an interesting target for drug development, as it would not only inhibit the viral replication but would also prevent the massive immunological response resulting of the over-activation of the host´s immune system, that can lead to damaging of uninfected cells and therefore worsening of the patient´s condition.
Our protein contains no additional amino acids at the N-terminus like proteins from competitors. Therefore, the protease has the authentic N-terminus which is part of the active site of the protein.
