^aCells were grown in TSS medium. GlutDH activity was assayed and expressed in units as described in Materials and Methods. Strains BB1268 (ΔgudB::tet) and BB1284 (ΔrocG::ble gudB1) were used for determination of RocG and GudB1 activities, respectively. All numbers are averages of at least two experiments, and the mean errors did not exceed 30%. 

^bND, not done.
