90% of the carbonic anhydrase (CA) activity recovered from Chlorogloeopsis fritschii cells, when broken under conditions which favour the isolation of carboxysomes, is particulate. Subsequent sucrose density gradient centrifugation of the carboxysome-containing pellet produced a sharp band of CA, well separated from the carboxysomes and thylakoids. The implications of these findings for the possible functions of carboxysomes and location of CA are discussed

  • Carbonic anhydrase
  • Chlorogloeopsis fritschii
  • carboxysomes
  • cyanobacteria
