abstract：:We have characterized the glucose transport system in the Kc cells of Drosophila melanogaster. The transporter is stereospecific and can be inhibited by both cytochalasin B and phloretin, with ki values of 4 microM and 30 microM for cytochalasin B and phloretin, respectively. Moreover, phlordzin does not affect uptake...
