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.

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

receptor_2

1st network : with amplifier 1 (RsmA-rsmY)

amplifier_1

Amplifier 1 : RsmA-rsmY system characterisation: (3 final plasmids)

Plasmid Mapping

On a pSB4K5 plasmid, we wanted to put the construction: pLAC_fha1_eCFP
amplifier_1
On a pSB3C5 plasmid, we wanted to put the construction: pLAC_RBS_RsmA On a pSB1A3 plasmid, we wanted to put the construction: pLAC_rsmY
amplifier_1

Biobricks involved

pLAC_RBS (BBa_I13601) => final length ≃ 90bp
pLAC (BBa_I13601) => final length ≃ 90bp
eCFP (BBa_E0422 or BBa_E0022) => final length ≃ 800bp
plasmid pSB4K5 => final length ≃ 2400bp
plasmid pSB3C5 => final length ≃ 2400bp
plasmid pSB1A3 => final length ≃ 2400bp

New parts

RsmA (iGEM Grenoble 2011) => final length ≃ 200bp
rsmY (iGEM Grenoble 2011) => final length ≃ 170bp
fha1 (iGEM Grenoble 2011) => final length ≃ 80bp
