FNR Promoter
2013-08-30T11:00:00Z
2015-05-08T01:09:15Z
Part sourced from the following study into the FNR promomoter:
"Transcriptional Regulation by Tandem-Bound FNR at Escherichia coli Promoters", Barnard et al.
This part is a standard FNR promoter. It has two FNR binding sites at -41.5 and at -91.5 with 0 being the transcriptional starting point of this promoter.
The promoter can be used in E.coli strains to induce protein expression in anaerobic environments. It is natively used to induce metabolic processes when the E.coli bacteria enter anaerobic environments.
The part can be used to express any protein sequence placed behind it.

To remove the EcoRI site we adapted the tail of the sequence which we had found in the above mentioned article. The EcoRI site was situated in at -132. We therefore removed the sequence from -132 to -116 and replaced it with a sequence of 4 base pairs namely: GGTA. We hoped that this adaptation would be of no influence on the efficiency of the promoter.

1ETF Protein Production Construct
2013-09-07T11:00:00Z
2015-05-08T01:09:15Z
The composite designed was something we devised ourselves although each of the separate parts was sourced from a different area. The sources for each of the relevant parts can be found on their respective pages.
This composite part has been built up from a number of separate BioBricks, the most prominent of which the FNR promotor and the 1ETF Protein sequence. The FNR promotor sequence enables us to bring the 1ETF protein to expression anaerobically. Almost all E.coli strains posses a form of this promotor to induce metabolic processes once the bacteria enters anaerobic regions. The 1ETF protein is a HIV protein which we are expressing with the sole purpose of using it as a CEST contrast agent.

No real considerations were made in the construction of this composite part. The main point of focus was the compatibility of each of the parts with each other and the E.coli bacteria. Furthermore we then had to ensure that the protein sequence was in frame with the promotor to ensure that expression would be performed correctly.

Ribosoom Binding Site
2013-09-07T11:00:00Z
2015-05-08T01:09:16Z
The DNA sequence for this part was obtained from the article holding the information about the FNR promotor we used:
"Transcription Regulation by Tandem-Bound FNR at E.coli Promoters" by Bernard et al.
This part holds the DNA sequence for the ribosoom binding site used in the large constructs by the TU-Eindhoven team in 2013. The RBS site was placed behind a FNR promoter sequence and was used to express a number of different proteins in anaerobic conditions. The protein sequence was placed immediately behind the RBS.

His-Tag and Thrombine Cleavage Site
2013-09-07T11:00:00Z
2015-05-08T01:09:16Z
The DNA sequence for this part was lifted directly from the pET28-a vector. This will allow us to use this part without further adaptations.
This construct contains the DNA sequence we used to provide a His-Tag and Thrombine cleavage site between our promoter and protein sequence. This will enable us to purify our protein after expression.

Spacer Sequence
2013-09-07T11:00:00Z
2015-05-08T01:09:16Z
This part was designed by ourselves. It was constructed by using a randomising a DNA sequence.
This part contains the DNA sequence for a spacer which can be placed at the end of a protein sequence. This will ensure for extra DNA base pairs between the end of the protein sequence and the terminator site. This has been done to ensure that no steric hindrance will occur from the use of the terminator.
