This year the iGEM team <a target="_blank" href="https://2017.igem.org/Team:CU-Boulder">CU Boulder</a> works with artificial compartments which consist of shell proteins containing a photoswitch amino acid. These compartments are supposed to break up into separate shell proteins releasing the protein captured inside the compartment. This could potentially act as next-generation drug delivery systems, biosensors, or as a solution to sequester diffuse and harmful environmental toxins. The iGEM team <a target="_blank" href="https://2017.igem.org/Team:CU-Boulder">CU Boulder</a> 2016 submitted the BioBrick containing the aminoacyl tRNA synthetase (aaRS) for the photoswitch amino acid. This year’s team helped us to realize our photoswitching project by sending us their aaRS and a small amount of the amino acid AzeF. In return, we transformed their parts EutS (<a target="_blank" href="http://parts.igem.org/Part:BBa_K2129001">BBa_K2129001</a>) and EutC-tagged FusionRed (BBa_XX) in <i>E.coli</i> DH5α and performed localization studies by fluorescence microscopy with our confocal laser scan microscope. | This year the iGEM team <a target="_blank" href="https://2017.igem.org/Team:CU-Boulder">CU Boulder</a> works with artificial compartments which consist of shell proteins containing a photoswitch amino acid.

Overview
Collaboration – Mentoring iGEM Team UNIFI 2017
Figure 1: Skype meetings with iGEM UNIFI for a two-way collaboration.
In return for the mentorship, iGEM UNIFI helped us characterizing two BioBricks. To make sure that Escherichia coli is able to take up the unnatural nucleoside triphosphates from the cultivation media we had to introduce a heterologous transporter. This is due to a lack of nucleotide transporters in E. coli. One of the BioBricks encodes a complete nucleotide transporter ptNTT2 (BBa_K2201000) originated from the algae Phaeodactylum tricornutum. The second BioBrick is a truncated version missing the N-terminal signal peptide (BBa_K2201001). This N-terminal signal peptide leads to some kind of toxicity in E. coli. Through cultivation experiments we wanted to investigate the extent of the toxicity by comparing the growth of the strain expressing the full version of PtNTT2 to the ones expressing the truncated version.
We started to cultivate the different strains in 50 mL media using flasks and measured the OD600 every 30 minutes during the exponential growing phase. Due to manual measurements our results showed big error values for the maximum growing rate µmax. This makes it hard to get a valid conclusion. iGEM UNIFI has the capacity to do the same cultivation experiment using a microscale bioreactor. This ensures automatic measurements for OD600 values which would decrease errors concerning µmax. This characterization from iGEM UNIFI would lead to a more accurate estimation of the toxicity of a full length version compared to a truncated version of PtNTT2.
Collaboration - Lokalization Study and Part Exchange with CU Boulder 2017
Figure 2: 3D-Animation of the fluorescence signal of E.coli cells transformed with EutC-tagged FusionRed from CU Boulder. The fluorescence is present in the whole cell.
Figure 3: 3D-Animation of the fluorescence signal of three E.coli cells cotransformed with shell protein EutS and EutC-tagged FusionRed from CU Boulder. The fluorescence is concentrated in the EutS-compartments.
We are very happy that they provided their aaRS to us to expand our toolkit and we hope that our results of the localization study are helpful for their further work.
