mSCARLET-I under control of ihfB800 promoter

Red fluorescent protein mScarlet-I expressed under control of the constitutive promoter of E. coli ihfB.

Introduction

This part is composed of the gene coding for the mScarlet-I (BBa_K2333414) red fluorescent protein, under control of the 800 first base pairs of the ihfB promoter (see BBa_K4197014. This promoter has been identified as a constitutive E. coli promoter (Weglenska et al., 1996). It was used for constitutive expression of fluorescent proteins in E. coli (Barthe et al., 2020) and appears as strong enough to permit sufficient expression of mScarlet-I without inclusion bodies.

Construction

The objective of the INSA-UPS 2022 team was to use the ihfB800 promoter to express mScarlet-I into E. coli Tuner (DE3) cells. The functionality of promoter and protein was confirmed as the mScarlet-I was successfully expressed (see BBa_K4197020 and BBa_K4197021).
