Transcriptional regulation of the extended PTS cluster genes of C. glutamicum cultures grown in liquid media containing glucose, fructose, or acetate. The strain RES167 was grown in liquid media containing glucose, fructose, or acetate. By RT-PCR the mRNA levels of the genes sugR, cg2116, ptsI, cg2118, fruK, ptsF, and ptsH of cultures grown in glucose (white bars) or fructose (grey bars) were compared to those of cultures grown in acetate containing media. Results are means of four measurements from two biological replicates. Standard deviations are indicated by error bars.
