Part:BBa_K1497019
fdeR (Naringenin binding protein) and fde operon regulatory domain FdeR is a homo dimeric protein from Herbaspirillum seropedicae. In present of naringenin, FdeR activates the specific promotor region upstream of the fdeR region and allow a strong gene expression.
We modified the naringenin biosensor from Siedler et al. by elimination of the internal EcoRI restriction site and replaced the CFP by the Biobrick Suffix. Based on this reporter protein and 3 different fluorescence proteins, we designed 3 new biosensors for in vivo detection and determination of naringenin.
=Usage and Biology
You can create your own naringenin sensor or your own naringenin dependent gene expression device as well. For these reasons use FdeR Biobrick K1497019 and clone your parts of interest (without RBS!) behind the device.
You can use the reporters for measuring naringenin concentrations in your samples.
Depending on which fluorophor you want to detect, you can use one of three biosensors:
GFP K1497020 mKate K1497021 CFP K1497022
