crr/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.
Cloning
The crr gene was amplified from gDNA of Salmonella typhimurium and cloned onto pSB1C3
