This report gives a comparison of the specificity of phosphate translocators in various plastids. Whereas the phosphate translocator of the C(3) plant spinach mediates a counter exchange between inorganic phosphate, dihydroxyacetone phosphate, and 3-phosphoglycerate, the phosphate translocators in chloroplasts from C(4) and CAM plants transport phosphoenolpyruvate in addition to the above mentioned metabolites. In plastids from pea roots the phosphate translocator also transports glucose 6-phosphate. This diversity of phosphate translocators is discussed in view of the special functions of the various plastids.
