(A) A schematic diagram of the membrane protein complex PSI in Synechocystis 6803 cells. The bold letters denote various polypeptide components (PsaA, PsaB, etc.) of PSI. The vertical arrows show the path of electrons in the core region of the PSI complex. (B) Immunological detection of various structural proteins of PSI in the thylakoid (TM) and plasma (PM) membranes in Synechocystis 6803. Fifty micrograms protein-containing sample was loaded in each lane. (C) Immunoblot analysis of three proteins that regulate biogenesis and stability of the PSI complex. TM: thylakoid membrane; PM: plasma membrane. Fifty micrograms protein-containing sample was loaded in each lane.
