Expression of genes coding for carbohydrate uptake systems in E. coli MG1655 grown under anaerobic versus aerobic conditions with glucose excess, normalized to anaerobic conditions. ptsG encodes EIIBCGlc; mglB, encodes a subunit of the galactose ABC transporter MglBAC; galP encodes galactose permease; malE encodes a subunit of the maltose ABC transporter MalEFG; manX encodes EIIABMan. Average data from 4 independent cultivations per strain and condition are given. Gene expression was normalized to the expression level under anaerobic conditions. The horizontal lines mark the significance levels; only changes above the solid line or below the dotted one were regarded as significant.
