FIG. 2.

Effect of the addition of CCCP on the uptake of [³H]TPP by M. smegmatis cells carrying plasmid pMtb312 (■, no CCCP addition; □, addition of CCCP) or the cloning vector pMD31 (⧫, no CCCP addition; ◊, addition of CCCP). CCCP at a concentration of 0.1 mM was added at the time indicated by the arrow. The results are the averages of three replicates, and error bars indicate standard deviations.
