mRFP1 fused to a TEV cleavage site cleaved


I : parts BBa_K3147004 function

The Montpellier 2019 team made this reporter gene construct in order to obtain a positive control for TEV mediated proteolysis of the ssrA tag fused the mRFP1 reporter (BBa_ K3147000). This construction produces mRFP1 fused in C-ter to a sequence corresponding to a TEV cutting site after cleavage (ENLYFQ).

II. Proof of function

This construction was cloned by Gibson Assembly in a pBbB8k (https://www.addgene.org/35363) backbone under the control of a pBAD promoter.

We compared the basal fluorescence of the strain NEB10β of E. coli transformed with the mRFP1-TEVcs construction to an E. coli NEB10β strain transformed with the mRFP1-TEVcs-ssrA construction. Fluorescence was quantified after arabinose induction at 1% with a plate reader overnight. Here are the fluorescence of mRFP-TEVcs-ssrA and mRFP-TEVcs at 30°C and 37°C.
