UniProtKB description:  Cysteine protease (PubMed:31306685). Displays a high level of diversity in substrate specificity at the P1-P1' cleavage site (PubMed:31306685). A hydrophilic P1 residue is preferred, with Gln or Arg strongly preferred (PubMed:31306685). Favors an Ile/Leu residue at the P2 position of substrates, with an overall higher preference for Leu (PubMed:31306685). The optimal tripeptide for cleavage is Pro-Leu-Gln, with cleavage occurring after the Gln residue (PubMed:31306685). Another optimal tripeptide is Val-Leu-Arg, which may imply that a hydrophobic residue at the P3 position of substrates is preferred (PubMed:31306685).
