UniProt code: P05994.

Organism: Carica papaya (Papaya).
Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliophyta; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Caricaceae; Carica.
Function: Thiol protease with a substrate specificity very different from the other thiol proteases.
Catalytic activity: Preferential cleavage: Gly-|-Xaa, in proteins and in small molecule substrates.
Enzyme regulation: Not inhibited by cystatin.
Miscellaneous: Substitution of the conserved Gly residue by Glu- 155 could possibly explain the unusual specificity.
Similarity: Belongs to the peptidase C1 family.
