Table 3. Uptake rates for M. smegmatis and M. tuberculosis towards hydrophilic solutes.

Quantification of uptake rates for glucose, serine and glycerol by the wt strains M. smegmatis SMR5 and M. tuberculosis H37Rv as well as the porin mutant M. smegmatis ML16. All assays were performed at 37°C at a final solute concentration of 20 μM. The M. smegmatis strains contained the empty plasmid pMS2. Uptake rates were determined from the kinetics shown in Figs. 3 and 4 for M. smegmatis and M. tuberculosis, respectively, and are expressed in nmol/min/mg cells.

SMR5 ML16 H37Rv
glucose 3.43 0.14 0.04
serine 1.41 0.53 0.13
glycerol 0.25 0.06 0.19
