Part:BBa_K2387054

mRFP controlled by inducible araC/pBAD promoter

mRFP is a red monomeric fluorescent protein. In this composite, its expression is regulated by the araC/pBad promoter and by a strong RBS. mRFP presents a maximum pick of excitation at 584 nm and a maximum pick of emission at 607 nm. mRFP was engineered from DsRed to grant it a monomeric conformation.

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 0.02% arabinose (Figure 1).

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.
