IntEnz Enzyme Nomenclature
EC 3.4.21.102

Names

Accepted name:
C-terminal processing peptidase
Other names:
CtpA gene product (Synechocystis sp.)
Tsp protease
photosystem II D1 protein processing peptidase
protease Re
tail-specific protease
Systematic name:
-

Reaction

Comments:

Proteolytic processing of the D1 protein of photosystem II is necessary to allow the light-driven assembly of the tetranuclear manganese cluster, which is responsible for photosynthetic water oxidation. The recognition of the substrate is mediated by a PDZ domain, a small protein module that promotes protein-protein interactions by binding to internal or C-terminal sequences of their partner proteins. Type example of peptidase family S41.
