Protein
Probable zinc metalloprotease EGY1, chloroplastic
Organism
Arabidopsis thaliana
Function
Membrane-associated and ATP-independent metalloprotease required for development of both thylakoid grana and well-organized lamellae in chloroplast. Required for the accumulation of chlorophyll and chlorophyll a/b binding (CAB) proteins (from both PS I and PS II) in chloroplast membranes, and for grana formation and normal chloroplast development. Involved in the regulation of nuclear gene expression in response to ammonium stress and interacts with ABA signaling. Carries out beta-casein degradation in an ATP-independent manner in vitro.
Similarity
Belongs to the peptidase M50B family.
