SDS–polyacrylamide gel electrophoresis of c rings that are isolated from thylakoid membranes of two cyanobacterial strains. Lane 1 shows the c ring from the alkaliphilic cyanobacterium Spirulina platensis and lane 2 shows the c ring from the freshwater cyanobacterium Synechocystis PCC 6803. Lanes 3 and 4 show the c14 and c11 rings from spinach chloroplasts and Ilyobacter tartaricus, respectively. Lanes 5 and 6 show c monomers of S. platensis and Synechocystis PCC 6803 obtained by trichloroacetic acid treatment of the rings. A standard gel marker is indicated on the left.
