“…In our assays Pftf was found to be an integral membrane protein, as is predicted by sequence analysis in both chloroplasts and chromoplasts, which is at variance with the originally assigned stromal localization. A related chloroplast FtsH has been cloned from Arabidopsis and demonstrated to be an integral membrane protein with proteolytic activities in chloroplasts (Lindahl et al, 1996;Ostersetzer and Adam, 1997). Pftf shares with FtsH and Yta10/Yta12 the presence of only one AAA domain, a zinc metalloprotease-binding domain, and a membraneanchoring domain (E. J.…”

“…In higher plants, chloroplastic FtsH has been shown immunologically to reside in thylakoid membranes, and a corresponding Arabidopsis cDNA ( FtsH1 ) was isolated (Lindahl et al, 1996). Subsequently, the latter's involvement in the degradation of unassembled thylakoid proteins was suggested (Ostersetzer and Adam, 1997). Later, the product of FtsH1 cDNA, when expressed as a soluble fusion protein, was shown to participate in vitro in the degradation of photodamaged D1 protein of the photosystem (PS) II reaction center (Lindahl et al, 2000).…”

“…Clp protease appears to be involved in degradation of unassembled proteins in the stroma (Halperin and Adam, 1996;Halperin et al, 2001a), in degradation of thylakoid membrane proteins in response to nutrient limitation (Majeran et al, 2000), and in shoot development (Kuroda and Maliga, 2003). FtsH is involved in the degradation of unassembled proteins in the thylakoid membrane (Ostersetzer and Adam, 1997), degradation of the oxidatively damaged D1 protein of PSII (Lindahl et al, 2000;Bailey et al, 2002;Sakamoto et al, 2002;Silva et al, 2003), and chloroplast development (Chen et al, 2000;Takechi et al, 2000;Sakamoto et al, 2002). The only reported activity of chloroplast DegP is the initial cleavage of the D1 protein of PSII during repair from photoinhibition .…”
