Our project, in essence, designs the perfect alarm clock. The presence of a strong wintergreen smell is used to help the user wake up, heightening their senses. At night, when no light is present, a banana odor produced will assist in calming down the user, helping them go to bed. This all occurs in the absence of electricity through pure biological systems. | Our project, in essence, designs the perfect alarm clock.

Overview
Our project, in essence, designs the perfect alarm clock. The presence of a strong wintergreen smell is used to help the user wake up, heightening their senses. At night, when no light is present, a banana odor produced will assist in calming down the user, helping them go to bed. This all occurs in the absence of electricity through pure biological systems.
This system is the combination of the MIT and University of Texas teams' projects from years past. We are making a combined genetic circuit with the smell of the bacteria (banana or mint) depending on the time of day (presence of light). The light receptor protein, obtained from photosynthetic algae, turns the banana smell on in the absence of light, and the mint smell on in the presence of light. In the agar of the plates we use for the final system we would need to include the substrates isoamyl alcohol and salicyclic acid.
In the dark, the EnvZ protein in the membrane protein complex cph8 (BBa_I15010) is more highly activated, which phosphorylates a greater amount of the transcription factor OmpR, which naturally occurs in E. coli. Large amounts of OmpR-P, in turn, will suppress the OmpF promoter (BBa_K116500), which controls the mint odor generator (BBa_J45004). OmpR-P will also activate the OmpC promoter (BBa_R0082), which controls the Banana odor generator (BBa_J45199). Thus banana smell at night and no mint odor generated. The opposite is intended to occur in the daylight. When a photon hits the receptor of cph8, EnvZ activity is reduced, causing less OmpR phosphorylation, causing activation of the OmpF promoter, yielding a mint odor, while the OmpC promoter is no longer activated, ceasing the production of the banana odor.
We will be co-transforming a single strain of E.coli with our two systems contained within two separate plamids. The images below have been presented as two separate systems for clarity sake, but both plasmids will exist in a single organism.

Parts
Light sensor protein or Cph8 (BBa_I15010)- contains coding region, location is well 20D plate 3 and is Kanamycin resistant. This part was taken from a UT Tech previous iGEM project. If a photon hits the light sensor Cph1 it will then inhibit EnvZ.
OmpC promoter (BBa_R0082)- A promoter for the banana gene sequence, it activates transcription of the banana smell gene when high amounts of OmpR-P are present, which occurs when there is no light.
Banana odor enzyme generator (BBa_J45199)- The banana smell generator contains an RBS, the coding region, two terminators. It was isolated from yeast used in alcohol fermentation which would give it its unique smell.
OmpF promoter (BBa_K116500)- A promoter for the mint gene sequence. It is activated in the day when low amounts of OmpR-P are present.
Ribosome binding site (BBa_B0030)- A ribosome binding site that will be attached to the mint odor generator.
Mint odor generator (BBa_J45004)- Contains the coding sequence for the Mint Odor Generator. This gene was isolated from petunia and snapdragon plants. It breaks down salicyclic acid into methyl sali to give it a mint smell.
Terminator 1 (BBa_B0010)- the first of the two mint terminators, ends transcription.
Terminator 2 (BBa_B0012)- the last of the mint terminators, ends the transcription.
Human Practices
Outreach
In early May team members Brandon Whitcomb and Tim Schaefer taught a lesson on genetic engineering and its societal impacts to three seperate second grade classes at Cottonwood Pint elementary school in Overland Park, Kansas.
The BVCAPS Research Kansas team took on the first annual CAPS Bioengineering Summer Camp and taught them the value of exposure and knowledge of bioengineering in a world fast heading in that direction. We presented our project to these students and presented the steps necessary to achieve a successful bacterial transformation.
In response to our work with these students we have verbal commitments from a good selection of the 23 students saying they would be interested in participating in iGem in the future.
On the Friday leading up to the freeze we took in one urban child who we found was fascinated by Biology and Bioengineering. He was quick to understand the practical uses of a lot of our lab equipment i.e. vortex machine, micro-pipets, centrifuge machine, and electrophoresis machine. At just 8 years old he took on the tasks we presented to him with flying colors and limited team member help.
