Effect of Reduction in Carbonic Anhydrase Activity Caused by Zinc Deficiency on CO2 Transfer Resistance

  • Chapter
Photosynthesis: Mechanisms and Effects

Abstract

Carbonic anhydrase (CA; EC.4.2.1.1) catalyzes the reversible conversion of CO2 to HCO3. CA has been recognized as an important enzyme that is closely associated with photosynthesis and the activity of CA can be specifically inhibited by zinc deficiency. In a previous study, we succeeded in estimating the magnitude of the CO2 transfer resistance (rr) from the intercellular space of mesophyll cells to the site of CO2 fixation in the chloroplasts (1). The purpose of the present study was to elucidate the relationship between the activity of CA and each component of mesophyll resistance and the mechanism of the specific inhibition of CA activity by using zinc deficient rice plants.
