Parts submitted to the registry

All our results are documented in our notebook and summarized in the partsregistry. Here we shortly describe what happened to give you an idea about the current status of the different subprojects. Please follow the links for more information.

Precipitator

[http://partsregistry.org/Part:BBa_K608404 BBa_K608404] IPTG-inducible Promoter with plastic binding domain-tagged GFP

[http://partsregistry.org/Part:BBa_K608406 BBa_K608406] Precipitator

The Precipitator is a new artificially designed LRR protein. It is meant as protein that binds Nickel ions with Histidines grouped on its surface. The bound Nickel can then precipitate His-tagged proteins. In our Lab in a Cell it should function as an adaptor between the plastic surface of pipettes and the His-tagged protein. Please look at our detailed description of the design layout in our modeling section. The sequence was synthesised and cloned into the iGEm vector. The submitted sequence was fully confirmed by sequencing.

[http://partsregistry.org/Part:BBa_K608407 BBa_K608407] Precipitator fused with GST tag

The Precipitator was fused with the C-terminus of our GST tag in order to extract and further test the construct for its Nickel binding affinity. We successfully cloned it together using the Gibson Assembly and then subsequently pasted it into the iGEM vector. The submitted sequence was partially confirmed by sequencing.

[http://partsregistry.org/Part:BBa_K608408 BBa_K608408] GST-tag

The GST-tag was PCR amplified from a pGEX vector with overhang primers including the iGEM restriction sites and then pasted into the iGEM vector. To verify the functionality of the construct we cloned it before a GFP sequence and expressed it with an IPTG inducible vector. Results see partsregistry page. The submitted sequence was partially confirmed by sequencing.

Green light receptor

[http://partsregistry.org/Part:BBa_K608101 BBa_K608101] CcaR, green light response regulator

The green light response regulator CcaR was amplified via PCR from
the whole Synechocystis sp. PCC 6803 genome and inserted into the pSB1C3 vector.

[http://partsregistry.org/Part:BBa_K608102 BBa_K608102] CcaS, green light receptor

[http://partsregistry.org/Part:BBa_K608151 BBa_K608151] translational unit of pcyA

Lysis cassette

[http://partsregistry.org/Part:BBa_K608351 BBa_K608351] (correct) temperature sensitive promoter

[http://partsregistry.org/Part:BBa_K608352 BBa_K608352] Bacteriophage Lysis Cassette with RBS

commons

At the beginning we had to assemble promoters and ribosome binding sites of different "strengths" (ie consensus identities)
in order to ensure proper and controlled expression of our parts.

The cloning procedure was time-consuming (circa two weeks), so we decided to
send our constructs to the registry. Herewith we hope to help others save some time.
We called these constructs PR to abbreviate "Promotor and RBS"

[http://partsregistry.org/Part:BBa_K608002 BBa_K608002] strong Promotor and strong RBS

[http://partsregistry.org/Part:BBa_K608003 BBa_K608003] strong Promotor , medium RBS

[http://partsregistry.org/Part:BBa_K608004 BBa_K608004] strong Promotor , weak RBS

[http://partsregistry.org/Part:BBa_K608005 BBa_K608005] medium Promotor , strong RBS

[http://partsregistry.org/Part:BBa_K608006 BBa_K608006] medium Promotor , medium RBS

[http://partsregistry.org/Part:BBa_K608007 BBa_K608007] medium Promotor , weak RBS

To quantify the strength of our PR-constructs we cloned GFP and RFP behind it
and quantified the protein output.
