Protein
Carboxyl-terminal-processing peptidase 2, chloroplastic
Organism
Arabidopsis thaliana
Function
Protease involved in the C-terminal processing of the chloroplastic D1 protein 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.
Similarity
Belongs to the peptidase S41A family.
