WebSep 22, 2010 · The strict dependence of thylakoid membrane formation on FtsH, as well as the high abundance of this complex (and of Clp) in etioplasts, strongly suggests that such proteolytic activity is indeed required. Our understanding of the molecular and structural events that occur during thylakoid membrane ontogeny in angiosperms is evidently …
WebAbstract. Current molecular analyses suggest that initial steps of the biogenesis of cyanobacterial photosystems progress in a membrane subfraction representing a biosynthetic center with contact to both plasma and thylakoid membranes. This special membrane fraction is defined by the presence of the photosystem II assembly factor PratA.
