mVenus controlled by inducible araC/pBAD promoter

mVenus is a bright yellow monomeric fluorescent protein. In this composite, its expression is regulated by the araC/pBad promoter and by a strong RBS. mVenus presents a maximum pick of excitation at 515 nm and a maximum pick of emission at 528. mVenus was engineered from YFP to grant it a faster maturation and to make more resistant to pH and chloride ions.

Functional Parameters

In order to test the functionality of this protein under the araC/pBad promoter, the absorbance and the fluorescence spectra were measured after induction with 0.002% arabinose (Figure 1).

Figure 1: On the left, E. coli BL21 without plasmid. On the right, E. coli BL21 expressing anm2CP induced by 0.2% arabinose.

This protein is part of a collection of split proteins developed for BiFC analysis and tested with the CpxR system (BBa_K2387032). These proteins were characterized through multiple experiments using as interacting proteins antiparallel synthetic leucine zippers. The proteins of this collection are the ones found in Table 1.
