产品介绍： FtsH belong to a family of ATP dependent peptidases. Localized in a chloroplast are following isoforms: FTSH1 (synonymes AAA, FTSH, FTSH Protease 1), Ftsh2 (VAR2, VARIEGATED 2), FtsH5 (VAR1, VARIEGATED 1), FtsH6 (FTSH PROTEASE 6), FtsH7, FtsH8. FtsH9. Localized in mitochondria are following isoforms: FtsH3, FtsH4, FtsH10, FtsH11.FtsH2 (VAR2) is a component of the ATP-dependent zinc metallopeptidase. It is involved in the thylakoids biogenesis and in the repair of damaged D1 subunit of photosystem II, a process that protects against cell death under high light conditions. VAR1 transcript and protein levels increase with light intensity and it forms a complex with VAR1. Mutants show a variegated phenotype, which decreases during development.
