Figure 2From: Characterization of the biotin uptake system encoded by the biotin-inducible bioYMN operon of Corynebacterium glutamicumBiotin transport by C. glutamicum. C. glutamicum WT(pEKEx3) was grown under biotin-limitation (open circles) or with excess biotin (closed circles) and C. glutamicum WT(pEKEx3-bioYMN) was grown with excess biotin (closed squares) as described in methods. Uptake rates were plotted as a function of substrate concentration and fitted according to the Michaelis-Menten equation.Back to article page
