WebFeb 22, 2024 · The thylakoid centers seem to be closely associated with both the plasmatic and the thylakoid membrane systems; hence, it is tempting to speculate that they play a role in the biogenesis of the thylakoids (Rast et al., 2015). The architecture of the thylakoid membrane system is variable among chloroplasts and cyanobacteria. WebIt is embedded in the thylakoid membrane via its N-terminal transmembrane domains, while the C-terminal protease domain is present at the stromal side.
