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
C-terminal processing peptidase. [EC: 3.4.21.102]
The enzyme shows specific recognition of a C-terminal tripeptide, Xaa- Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr, and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. A typical cleavage is -Ala-Ala-|-Arg-Ala-Ala- Lys-Glu-Asn-Tyr-Ala-Leu-Ala-Ala.
  • In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II; this proteolytic processing is necessary to allow the light-driven assembly of the tetranuclear manganese cluster, which is responsible for photosynthetic water oxidation.
  • Belongs to peptidase family S41.
