FIG. 5.

Genetic organization of the two ABC transporter systems for l-lysine uptake in P. putida KT2440. (Top) Organization of the l-lysine transport system inactivated in mutant rei2-6; (bottom) organization of the l-lysine transport system inactivated in rei2-7. Genome organization is shown according to the findings of Nelson et al. (33). The number of amino acids of each translated product is given below the gene. BP stands for periplasmic binding protein, and ABC stands for ATP-binding protein. The function of the products encoded by adjacent ORFs in both loci is unknown.
