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 two systems in E. coli. Please go to our wiki page ([http://2017.igem.org/Team:Mingdao/Demonstrate Mingdao iGEM 2017]) for more information.
