Best Integrated Human Practices

Early contacts with experts in the field motivated us to host a workshop on “Expanding the Genetic Code” to facilitate discussions on current issues related to our topic. We incorporated these insights by submitting a comprehensive scientific review concerning biosafety issues in iGEM and the science in general. In addition, we created a report on Chances and Implications of an Expanded Genetic Code.

Best Education and Public Engagement

Throughout our project, we explained our topic to the public and the scientific community on multiple occasions and engaged in fruitful discussions. Furthermore, we raised awareness for the chances of synthetic biology by cooperating with a number of initiatives and programs, including the “6th CeBiTec Pupils Academy”, “Teutolab Biotechnology”, the street science festival “GENIALE” and through collaboration with the biotechnological student’s initiative btS e.V.

Best Measurement

Our toolbox for the incorporation of non-canonical amino acids provides innovative new methods for the characterization of all protein encoding parts. With the help of non-canonical amino acids, the subcellular localization of a protein can be investigated. Measurement of intramolecular distances, protein immobilization and light regulation and modification enables sophisticated characterization of parts.

Best Modeling

Via structural prediction combined with recent knowledge from the scientific body, we generated optimized synthetases, which are intended to recognize synthetic amino acids. This builds the foundation of a promising and powerful alternative to synthetase selection in the lab.

Best applied design

Inspired by the highly specific condensation reaction of D-luciferin from the firefly Photinus pyralis, we came up with the idea to synthesize our own new amino acid, combining organic chemistry, computational modelling, and molecular biology. We designed the novel synthetic amino acid Nγ cyanobenzothiazolyl L asparagine (CBT-asparagine), which cyano group undergoes a condensation reaction with the 1,2-aminothiol group of Nε L cysteinyl L lysine (CL).

Best Basic Part

For our project, we characterized the structure, kinetics, dynamics and subcellular localization of PtNTT2 and different PtNTT2 variants. Therefore, we applied bioinformatic prediction tools, confocal laser scanning microscopy, SDS-PAGE, Western Blot, MALDI-TOF as well as HPLC-MS. In the future, advanced endosymbiotic systems or novel biosafety mechanisms can be developed based on this part.

Best Composite Part

Best Part Collection

Our part collection expands the possibilities for advanced protein design, utilizing novel amino acids with diverse chemical abilities. We provide six different aminoacyl-tRNA synthetases for the translational incorporation of non-canonical amino acids to the iGEM community.

Best Software Tool

Our sophisticated software suite is composed of two connected modules for the analysis of unnatural base pairs in a specified target sequence: M.A.X and iCG. We postulate that our suite is also applicable for the study of DNA modifications and epigenetics.

Best Hardware

We designed and constructed a multifunctional LED panel in a 96-well microtiter plate format through multiple rounds of optimization. This device enables the sophisticated irradiation of samples with a high resolution of light of different wavelengths and intensities. Using our self-written Android application, complex illumination protocols can be programmed and send to the device via bluetooth.

Integrated Human Practices

Throughout our project we got advice and support by over thirty experts that influenced our work very much. We organized a conference about the expansion of the genetic code and wrote a report about the chances and implications of an expanded genetic code. See all the human practices we integrated into our project here.

Improve a previous part or project

We improved the validation system for aminoacyl-tRNA synthetases for ncAAs from Austin Texas 2014 (BBa_K1416004)

Model your project

We successfully modeled several protein sequences for our synthetases to incorporate the new synthetic non-canonical amino acid CBT-asparagine and 2-nitrophenylalanine. See the results of our modeling here.

Demonstrate your work

We were able to integrate and detect the unnatural bases in the DNA sequences by software modification of nanopore sequencing. We also expanded the genetic code by providing a toolkit of some evolved synthetases. These are able to incorporate noncanonical amino acids into any kind of protein and proof their functionality. See a summary of our achievements here.

Validated Part / Validated Contribution

In our project we used and created a lot of different parts. We are especially proud of our part BBa_K2201004 that worked just as expected and was well characterized and validated by us.

Collaboration

Throughout our project we collaborated with many iGEM Teams to improve our work and help each other. Especially our part exchange with the CU Boulder team and the mentoring of the new iGEM team UNIFI was very important for us. See the summary of our collaborations here.

Human Practices

During the last months we had a lot of interactions with the public trying to convey the aspects of our work and project. For example we worked with pupils at the GENIALE or our yearly pupil’s academy and organized a literature workshop about synthetic biology. We had appearances at the radio, created a little biotechnology quiz show for a student initiative and even wrote a biosafety report. All silver human practices are collected here.

Register and attend

We registered for the competition in March and are proud to be able to attend the Giant Jamboree. We will without doubt have a lot of fun!

Deliverables

We have met all the required deliverables as you can see in our team wiki, our project attribution, our team poster, our presentation on the 12th of november, our safety and judging forms, our part page and our submitted samples.

Attribution

We created an Attribution site where we listed and thanked all the people who supported us with advice and material throughout our project. If not mentioned specificially we have done the work ourselfs and the results are due to our own work.
