Week 26: June 25th to July 01st

For the detection module, we decided to work on a modified membrane receptor. It consists of two merged E. coli membrane receptors. The extracellular part is the extracellular part of Tap, a dipeptide membrane receptor. The cytoplasmic part is the cytoplasmic part of the EnvZ receptor, which has the ability to activate OmpR (by phosphorilation) which is a transcription factor.

receptor


It will be a proof of concept for a bigger system which is a complete pathogene detection module :
