Figure 1From: Modeling and analysis of flux distributions in the two branches of the phosphotransferase system in Pseudomonas putidaThe PTS reactions in P. putida . The C branch of the PTS is shown on the left hand side from PEP (reaction r4) while the second branch is shown on the right hand side (reactions r1−r3). The phosphryl group from the final protein in the second branch, PtsN is not metabolized. However, there is evidence that cross talk occurs between the two branches. The C branch transfers the phosphryl group to the second branch directly to PtsN (reaction r5).Back to article page
