  • Title: Glucose transport activity in isolated plasma membrane vesicles from Saccharomyces cerevisiae.
    Author: Franzusoff AJ, Cirillo VP.
    Journal: J Biol Chem; 1983 Mar 25; 258(6):3608-14. PubMed ID: 6339489.
    Abstract:
    Purified plasma membranes prepared from yeast cells by mechanical agitation with glass beads exhibit no detectable sugar transport activity. However, the addition of phospholipid (asolectin) liposomes to the purified plasma membranes followed by freezing, thawing, and brief sonication produces membrane vesicles which exhibit D-glucose-specific transport activity. The characteristics of zero trans, equilibrium exchange, and influx counterflow exhibited by the membrane vesicles are similar to those of intact cells.
