Protein: Caricain (protease omega) from Papaya (Carica papaya) [TaxId: 3649]

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: Cysteine proteinases [54000]
    consists of one alpha-helix and 4 strands of antiparallel beta-sheet and contains the catalytic triad Cys-His-Asn
  4. Superfamily: Cysteine proteinases [54001]
    the constitute families differ by insertion into and circular permutation of the common catalytic core made of one alpha-helix and 3-strands of beta-sheet
