โœฆ Synopsis


Several functionally distinct families of transport proteins share the general structural motif of twelve transmembrane domains. The number of membrane proteins known to possess this common feature continues to expand with the cloning of transporters for various neurotransmitters, nucleosides, osmolytes and basic amino acids, in addition to the previously defined families of facilitative and sodium-driven sugar transporters.

## Abstract Amino acids are compartmentalized in the vacuoles of microorganisms and plants. In __Saccharomyces cerevisiae__, basic amino acids accumulate preferentially into vacuoles but acidic amino acids are almost excluded from them. This indicates that selective machineries operate at the vacuo
