ABSTRACT
Cyanobacteria are autotrophic prokaryotes with the capacity for photosynthesis. Cyanobacterial cells resemble the chloroplasts of plants in terms of both membrane structure and glycerolipid composition (1). There are three types of membrane in cyanobacterial cells: the plasma membrane, the outer membrane, and the thylakoid membrane. The thylakoid membranes are closed systems and are separate from the plasma membrane (1,2). This architecture corresponds to that of the eukaryotic chloroplast, which has inner and outer envelope membranes and thylakoid membranes.
