FunFam 87: Kallikrein 8 (Neuropsin/ovasin)

There are 1 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
Kallikrein 8. [EC: 3.4.21.118]
Cleavage of amide substrates following the basic amino acids Arg or Lys at the P1 position, with a preference for Arg over Lys.
  • Activated by removal of an N-terminal prepropeptide.
  • The highest amidolytic activity is observed using Boc-Val-Pro- Arg-|-7-amido-4-methylcoumarin, which is a substrate of alpha- thrombin.
  • Substrates lacking basic amino acids in the P1 position are not cleaved.
  • Degrades casein, fibronectin, gelatin, collagen type IV, fibrinogen, and high-molecular-mass kininogen and is associated with diseases such as ovarian cancer and Alzheimer's disease.
  • Belongs to peptidase family S1A.
