Figure 1. PpgK is required for normal growth with glucose as sole carbon source.

Growth of wt Mtb (A) and ΔppgK (B) in carbon defined media with 0.4% glycerol (squares), 0.4% glucose (circles) or no carbon (asterisks). Open circles depict growth of the complemented mutant in glucose containing medium. (C) Growth of wt and ΔppgK in response to increasing glucose concentration. Data represent two to three independent experiments.
