Electrophoretic mobility of the GntR-operator complexes. Increasing amounts of purified GntR were added to a 456-bp gntT fragment containing the putative regulatory region of the gntT gene in the absence or presence of different concentrations of gluconate. In the presence of GntR, two GntR-operator complexes (R1 and R2) were formed. F, free DNA. All samples contained 8.1 nM gntT DNA and the designated concentrations of GntR and gluconate.
