Abstract
EMD-IT-5914 (5-dimethylamino-methylene-2-oxo-4-phenyl-2,5-dihydrofurane-carbonitril-(3)) inhibited chlorophyll a formation almost completely and chlorophyll b and total carotenoids up to 80% of the control, but did not appreciably affect the activity of the enzyme system succinyl-CoA synthetase/δ-aminolevulinic acid synthetase. The activity of δ-aminolevulinic acid dehydratase was not found limiting. In contrast, the herbicide strongly inhibited the activity of porphobilinogenase, and the reaction kinetics pointed towards a non-competitive type of inhibition. The results are discussed in relation to the possible role of EMD-IT-5914 in chlorophyll biosynthesis.
