GluP contributes to glucose export. (A) A model of import-export of glucose by B. subtilis depicts the role of GluP as glucose exporter, as shown by right panel. Left panel indicates single or multiple eliminations (red or green cross) of proteins used in this study. Green crosses were part ptsGHI::erm mutation. (B) Glucose content in 50 mM trehalose supplemented LB medium of the wild type cells or various genotypes of B. subtilis. Standard deviation of two independent experiments is indicated.
