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.

CP29-RBS-aeBlue-RBS-STM1128-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. 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.

In order to express the genes in E. coli for demonstration and in probiotics for proof-of-concept in a real world. We chose promoter CP29 that is a strong constitutive promoter working well in both E. coli and Lactobacillus spp1. The biobrick part, CP29-RBS-aeBlue (BBa_K1033280) was used and to be assembled with the transporter genes.


Cloning: Promoter CP29-RBS-aeBlue (BBa_K1033280) was assembled with RBS-STM1128-TT/pSB1C3 (BBa_K2230025)


Function: An active low-affinity glucose transporter system. Promoter CP29 is a continuous and strong promoter which works well in both E. coli and Lactobacillus spp. The blue protein encoded by aeBlue gene acts as indicator for the gene expression in the transgenic strain. This device can help E. coli and Lactobacillus spp. efficiently take up and retrieve glucose in the environment.
