The universal stress protein A is a response of Escherichia coli cells to growth arrest, and its lacking generates cells with defective growth. For more information about this important protein, please feel free to visit the respective Wikigenes page (https://www.wikigenes.org/e/gene/e/948007.html).

The universal stress protein A promoter (also as known as PuspA) is a well characterized promoter element, inducible under several stress conditions (Prytz et al. 2003; Dyk et al. 1995; Nyström and Neidhardt 1992; 1994). This genetic element is dependent to sigma-70 factor (Nyström and Neidhardt 1992; 1994). Its regulation is done through the concentration of a specific stationary phase allormone, guanosine-5'-diphosphate-3'-diphosphate (ppGp), as described elsewhere (Farewell et al. 1998b). The ppGp activate the transcription of downstream elements through a positive regulation of the β-subunit of RNA polymerase. In this sense, the PuspA element is considered a stationary phase promoter. However, in the work of Prytz et al. (2003) a constitutive transcription promotion was observed.

Diverse conditions make the Escherichia coli cell enter to stress state, like heat shocks, starvation, osmotic stress, ultraviolet light and other conditions. In these situations, the RNA polimerase sigma factors (ropS) trigger the expression of chaperones and other stress protector molecules, in order to help the cell survive. Previous works have showed the power of the element PuspA, like shown in the Table 1.

            our project consists in the development of an alternative repellent of that currently sold in the market and more or equally effective in preventing mosquitoes bites transmitted diseases. The main compound in current repellents is DEET (N,
 
            N-diethyl-m-toluamide), a toxic molecule which at certain concentrations could be lethal, and therefore must have strict control on their use in products. The main characteristic of our repellent is the long duration when compared to other
 
            products and the replacement of the compound DEET by D-limonene. Instead, the D-limonene has low toxicity, is highly volatile and present a pleasant smell.</p>

Achievements

What we do

Overview

During laboratory activities realized by UFSCar-Brasil team, was obtained different results for the proposed project, as well as the contribution with new biobricks for registry and new protocols for scientific community use in forward projects. Based on molecular biology, bioinformatics and microbiology techniques, our Team could propose protocols and biobricks, which assist obtaining protein of difficult expression through the UspA promoter, as well as maintaining bacterial viability at room temperature by plasmolysis induced polyethylene glycol. Thus, we believe that with the expansion of synthetic biology to market manufactures, our protocols represent an important tool in enabling bacteria genetically engineered shelf products.

Another important point refer to the following project's module, characterized by overexpression of chaperones during cell growth and the utilization of a biosafety method as Killswitch; Developed by UFSCar-Brasil team, these modules can also represent important tools that envisaged the viability and theoretical basis of the project. We believe that, although many structural and funding problems, attach ourselves to the iGEM spirit and we achieved great achievements, and through impressive results in the laboratory, which are described below, contribute to the development of synthetic biology.

Parts

Here UFSCar-Brasil presents submitted parts to registry, allied to those used by us. In this sense, we submitted 11 new biobricks, being: 3 intermediate parts, 2 composite parts and 6 new simple parts. Our main goal was to design, build and test UspA promoter considered our best part.

Figure 1: Genetic circuit of Bug Shoo.

Result

Here we presented all results of our work. We obtained new biobricks, generated characterization information. Although do not achieve a functional prototype, we design mathematical methods and lab protocols to further testings. We also report all steps of biobricks and testing obtaining. Finally, we also reported plasmolysis experiment, where we could observe a great viability after 7 weeks using a cost effective and simple treatment, which could help transpass in the future our manufacturing tracking project into a real product.

Judging Criteria

Judging criteria are presented allied to our achievements showing how great our work was!
