PreScission Protease

PreScission Protease is a fusion protein of glutathione S-transferase (GST) and human rhinovirus (HRV) type 14 3C protease. The optimum recognition site for this enzyme is the sequence Leu-Glu-Val-Leu-Phe-Gln/Gly-Pro (LEVLFQ/GP) and cleavage occurs between the Gln and Gly-Pro residues. Substrate recognition and cleavage are likely to be dependent not only upon primary structural signals, but also upon the secondary and tertiary structures of the fusion protein as well.
