Indole Inducible System

The indole-inducible sensing system PpTrpI/PPP_RS00425 originates from Pseudomonas Putida KT2440 which was identified and characterized by Matulis et al. (2022). The system below includes the nucleotide sequence containing the trpI gene, encoding the LysR family transcriptional regulator (locus tag PP_RS00430), and intergenic region PP_RS00430/PP_RS00425, assembled in construct pPM0081. The system exhibits a strong affinity for indole, which activates the system, and is strictly specific.

In literature, an increase in indole concentration in fecal samples was found to be correlated with depressive symptoms. In our project, we aimed to create a microbial sensor of the gut to aid in the diagnosis of Major Depressive Disorder (MDD), and by measuring fluorescence intensity, this system will allow us to detect the levels of indole.

Although we were unable to test our novel system in the wet lab, the article referenced above by Matulis et al. (2022) presented results on the fluorescence detected in response to different concentrations of indole.1
