title: Determination of compartmented metabolite pools by a combination of rapid fractionation of oat mesophyll protoplasts and enzymic cycling.
abstract: In vivo pool sizes of a range of metabolites have been determined in subcellular fractions of darkened and illuminated mesophyll protoplasts of Avena sativa L. These estimations were made by combining a method of rapid protoplast fractionation with enzymic cycling techniques. Results are given for reduced and oxidized pyridine nucleotides, triose phosphates, 3-phosphoglycerate, inorganic phosphate, aspartate, malate, oxaloacetate, glutamate, 2-oxoglutarate, and citrate, from chloroplasts, mitochondria, and a fraction representing the remainder of the protoplast. The results indicate distinct differences of compartmented levels of certain metabolites between darkened and illuminated protoplasts.
