Since the initial discovery showing that ADPglucose (ADPG) serves as the universal glucosyl donor in the reaction catalyzed by starch synthase, the mechanism of starch biosynthesis in both leaves and heterotrophic organs has generally been considered to be an unidirectional process wherein ADPG pyrophosphorylase (AGPase) exclusively catalyzes the synthesis of ADPG and acts as the major limiting step of the gluconeogenic process. There is however mounting evidence that ADPG linked to starch… CONTINUE READING
