Protein: ATP-dependent zinc metalloprotease FTSH 5, chloroplastic (AtFTSH5) (EC 3.4.24.-) (Protein VARIEGATED 1) (Q9FH02)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Part of a complex that function as an ATP-dependent zinc metallopeptidase. Involved in the thylakoid formation and in the removal of damaged D1 in the photosystem II, preventing cell death under high-intensity light conditions. Not involved in the degradation of the light-harvesting complex of photosystem II (LHC II) or in thermotolerance.
Subcellular location: Plastid, chloroplast thylakoid membrane {ECO:0000269|PubMed:12167156, ECO:0000269|PubMed:14630971, ECO:0000269|PubMed:18431481}; Single-pass membrane protein {ECO:0000269|PubMed:12167156, ECO:0000269|PubMed:14630971}; Stromal side {ECO:0000269|PubMed:12167156, ECO:0000269|PubMed:14630971}.
