Salmonella typhimurium LT2 has two glucose-specific transporter systems, PTS system and sodium/glucose cotransporter. PTS system contains two subunits IIA encoded by crr and IIBC by ptsG which are assembled to a high-affinity active transporter. The other is a Na+/glucose cotransporter encoded by STM1128 that contributes to facilitated transport with lower glucose affinity. Based on our research, the glucose transporter of Salmonella has a lower Km compared to human small intestine, Staphylococcus and E. coli, indicating a higher efficiency for glucose uptake. In our project, we created the glucose transporter device and genetically engineer microbes with these two systems.

RBS-crr-RBS-ptsG-TT/pSB1C3

Salmonella typhimurium LT2 has two glucose-specific transporter systems, PTS system and sodium/glucose cotransporter. PTS system contains two subunits IIA encoded by crr and IIBC by ptsG which are assembled to a high-affinity active transporter. The other is a Na+/glucose cotransporter encoded by STM1128 that contributes to facilitated transport with lower glucose affinity.


Research

Based on our research, the glucose transporter of Salmonella has a lower Km compared to human small intestine, Staphylococcus and E. coli, indicating a higher efficiency for glucose uptake. In our study, we demonstrated glucose absorption ability by overexpressing each of these two systems from Salmonella in E. coli. Please go to our wiki page ([http://2017.igem.org/Team:Mingdao/Demonstrate Mingdao iGEM 2017]) for more information.
