Changing Kinetic Properties of Fructose-1,6-bisphosphatase from Pea Chloroplasts during Photosynthetic Induction.

I A Marques1, L E Anderson.   

Abstract

After dark-light transitions, there is a delay in photosynthetic CO(2) fixation by isolated pea chloroplasts in the range of some minutes. In order to assess the physiological significance of light modulation of enzyme activity in the control of induction, we made estimates of the kinetic parameters of fructose-1,6-bisphosphatase immediately upon release from pea chloroplasts in the dark and after illumination for various time periods. The Michaelis constant for fructose-1,6-bisphosphate decreased and maximal velocities increased during induction. It seems likely that light activation of this enzyme is one of the factors contributing to the overcoming of the lag period in photosynthetic CO(2) fixation.
