【 摘 要 】

Evidence is provided that amyloplasts from pea roots contain a translocator which transports, in a counter exchange mode, phosphate, glucose 6-phosphate, dihydroxyacetone phosphate and 3-phosphoglycerate. The translocator has a low affinity for 2-phosphoglycerate and glucose 1-phosphate. Metabolite transport was measured by silicone oil filtering centrifugation either directly by uptake of radioactive labelled compounds or indirectly by back exchange.
