WebJan 5, 2024 · the thylakoid membrane-bound FtsH5 and FtsH2 have dual functions in the maintenance of photosynthetic complexes. The initiation of (1)O2 signaling in grana margins depends on EX1 and the ATP-dependent zinc metalloprotease FtsH. As FtsH cleaves also the D1 protein during the disassembly of damaged PSII, EX1- and (1)O2-mediated … WebJun 1, 2006 · Further insight into the heteromeric nature of the FtsH complex came recently from the analysis of a series of double mutants [39, 41••].Inactivation of closely related pairs (FtsH1 plus FtsH5 [‘Type A’] or FtsH2 plus FtsH8 [‘Type B’]) resulted in a heterotrophic albino phenotype [41 ••].Moreover, in the absence of one pair of duplicated genes, the … directly observed treatment tb
