Abstract
Dark fixation of CO2 in homogenates prepared from soybeans, barley, and trifoliate orange leaves with phosphoenolpyruvate, ribose-5-phosphate, and glucose-6-phosphate as substrates indicated greater activities for plants slightly Fe deficient than for plants supplied adequate iron. Chelating agents tended to increase the activities and Fe+++ added to homogenates decreased the activity. The latter was reversed by chelating agents. The inhibition with Fe was shown to be competitive.This publication has 12 references indexed in Scilit:
