Relative gene expressions of C. glutamicum fructose-PTS cluster genes in dependence on the regulatory genes sugR and cg2118. The C. glutamicum strains LG01, LG02, and RES167 were grown in liquid media containing acetate as sole carbon source. By RT-PCR the mRNA levels of the fructose-PTS cluster genes ptsI, cg2118, fruK, ptsF, and ptsH of the mutant strains LG01 and LG02 were compared to those of RES167. Due to the deletion of the cg2118 coding region, the expression of the truncated cg2118 gene in the mutant LG02 could not be determined. Results are means of four measurements from two biological replicates. Standard deviations are indicated by error bars.
