PHYSIOLOGICAL AND MOLECULAR ASPECTS OF THE INORGANIC CARBON-CONCENTRATING MECHANISM IN CYANOBACTERIA

This paper reviews progress made in elucidating the inorganic carbon concentrating mechanism in cyanobacteria at the physiological and molecular levels. Emphasis is placed on the mechanism of inorganic carbon transport, physiological and genetical analysis of high-CO2-requiring mutants, the polypeptides induced during adaptation to low CO2, the functional significance of carboxysomes, and the role of carbonic anhydrase. We also make occasional reference to the green algal inorganic carbon-concentrating mechanism.
