Malic Enzyme Activity in Apple Fruit

Nature volume 196, pages 387–388 (1962)Cite this article

Abstract

THE capacity of apple fruit to decarboxylate malic acid oxidatively (the malate effect) is evident early in apple fruit ontogeny1, as well as in the stages characterized by the climacteric and post-climacteric phases of fruit respiration2. The stoichiometric characteristics of the malate decarboxylation reaction1 and the symmetrical distribution of carbon-14 in malic acid resulting from 14CO2 fixation in apple fruit3 suggested the malic enzyme may function in both reactions. This investigation was initiated to determine if malic enzyme is responsible for malate decarboxylation and carbon dioxide fixation into malic acid in apple fruit.
