There are 7 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.

Pepsin A.
[EC: 3.4.23.1]
Preferential cleavage: hydrophobic, preferably aromatic, residues in P1 and P1' positions. Cleaves 1-Phe-|-Val-2, 4-Gln-|-His-5, 13-Glu-|-Ala-14, 14-Ala-|-Leu-15, 15-Leu-|-Tyr-16, 16-Tyr-|-Leu-17, 23-Gly-|-Phe-24, 24-Phe-|-Phe-25 and 25-Phe-|-Tyr-26 bonds in the B chain of insulin.

Gastricsin.
[EC: 3.4.23.3]
More restricted specificity than pepsin A, but shows preferential cleavage at Tyr-|-Xaa bonds. High activity on hemoglobin.
|
4 | B9RG92 B9RM62 B9S098 B9SCN7 |
Nepenthesin.
[EC: 3.4.23.12]
Similar to pepsin, but also cleaves on either side of Asp and at Lys-|-Arg.
|
3 | P69476 Q766C2 Q766C3 |
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.
|
2 | A0A097NUZ4 A0A0M3R844 |
Proteasome endopeptidase complex.
[EC: 3.4.25.1]
Cleavage of peptide bonds with very broad specificity.
|
1 | A0A1E5WFF7 |
Type 1 galactoside alpha-(1,2)-fucosyltransferase.
[EC: 2.4.1.69]
GDP-beta-L-fucose + beta-D-galactosyl-(1->3)-N-acetyl-beta-D- glucosaminyl-R = GDP + alpha-L-fucosyl-(1->2)-beta-D-galactosyl-(1->3)-N- acetyl-beta-D-glucosaminyl-R.
|
1 | G0R492 |
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.
