Abstract
The role of the vacuole for cellular compartmentation of sulfur-contai ning compounds was investigated using vacuoles isolated from barley me sophyll protoplasts. In addition to transport functions for sulfate an d methionine, a MgATP-activated translocator allows for uptake of oxid ized - but not of reduced - glutathione from the surrounding medium. C ysteine is only taken up at a low basal rate which can be attributed t o diffusion through the lipid membrane.
