pAceB-sfGFP-Term

Promoter from E. coli that controls the AceB gene, involved in iron uptake.


HELLO WORLD


This promoter sequence contains a RBS and a FUR binding site, although it is not clearly possible to identify them precisely. It has been shown to downregulate the expression of sfGFP or any gene down-stream in the presence of iron in the range: 10-7 to 10-4 mol.L-1

FUR (Ferric Uptake Regulation) is a transcriptional repressor of genes involved in iron homeostasis. In presence of iron FUR will be linked to the iron. This modification of conformation will induce a dimerization of FUR. Then the dimeric FUR will bind to the DNA in a Fur Binding Site and inhibit the mRNA transcription.

To caracterize our constructions we use this Fur binding site merged with a super fold GFP to the power of inhibition of the Fur binding site.

Why would you use this part?

This part allows the characterization of the AceB promoter region thanks to the sfGFP downstream.
