FunFam 22834: Aspartic protease

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Rhizopuspepsin. [EC: 3.4.23.21]
Hydrolysis of proteins with broad specificity similar to that of pepsin A, preferring hydrophobic residues at P1 and P1'. Clots milk and activates trypsinogen. Does not cleave 4-Gln-|-His-5, but does cleave 10-His-|-Leu-11 and 12-Val-|-Glu-13 in B chain of insulin.
  • From the zygomycete fungi Rhizopus chinensis and R.niveus.
  • Belongs to peptidase family A1.
  • Formerly EC 3.4.4.17, EC 3.4.23.6, EC 3.4.23.9 and EC 3.4.99.25.

    2 Q02016 Q02017
    Mucorpepsin. [EC: 3.4.23.23]
    Hydrolysis of proteins, favoring hydrophobic residues at P1 and P1'. Clots milk. Does not accept Lys at P1, and hence does not activate trypsinogen.
    • Isolated from the zygomycete fungi Mucor pusillus and M.miehei.
    • Belongs to peptidase family A1.
    • Formerly EC 3.4.4.17 and EC 3.4.23.6.
    1 K4F4I1
    Gly-Xaa carboxypeptidase. [EC: 3.4.17.4]
    Release of a C-terminal amino acid from a peptide in which glycine is the penultimate amino acid, e.g. Z-Gly-|-Leu.
    • Belongs to peptidase family M20A.
    • Formerly EC 3.4.2.3, EC 3.4.12.8 and EC 3.4.17.9.
