ICE Pro
In vivo Continuous Evolution in Prokaryote
The aim of our project this year is to build an efficient system that is able to evolve biological parts with new desirable functions or features.
As Professor Dobzhansky goes, Nothing in biology makes sense except in the light of evolution[1], and we believe this is of no exception in the field of Synthetic Biology. The build-test-debug circle after rational design is one of the most critical concepts in biology engineering. However, after decades of development, this process is still slow, laborious and hard to manipulate due to the vast complexity of biological systems. Interestingly, we consider evolution as a possible solution, because the mutate-selection-survive process in natural selection quite resembles the build-test-debug circle.
So this year, we came up with the ICE Pro, In vivo Continuous Evolution in Prokaryotes, giving it a first try to bring evolution to Synthetic Biology. We sought to engineer Ll.trB group II intron from Escherichia coli (E. Coli) into a one-step high-throughput mutagenesis generation and screening machine. Ll.trB is a special reverse-transcription transposon, with the ability to transcribe into mRNA, and then reverse-transcribe into DNA before inserting back to the genome[2]. Our rationale is that, because of the lack of mismatch repair and the quick proliferation rate of E. Coli, a large mutation library can be built in a short time. Subsequently, a quick and easy screening can be achieved by posing a selection pressure in the environment. We believe this system can be used to optimize almost any proteins useful in any fields from medical to food, from energy to environment. What’s more, ICE Pro is also able to evolve other parts, such as promoters.

Welcome to iGEM 2017!
Your team has been approved and you are ready to start the iGEM season!
Before you start:
Please read the following pages:
Styling your wiki
You may style this page as you like or you can simply leave the style as it is. You can easily keep the styling and edit the content of these default wiki pages with your project information and completely fulfill the requirement to document your project.
While you may not win Best Wiki with this styling, your team is still eligible for all other awards. This default wiki meets the requirements, it improves navigability and ease of use for visitors, and you should not feel it is necessary to style beyond what has been provided.
Wiki template information
We have created these wiki template pages to help you get started and to help you think about how your team will be evaluated. You can find a list of all the pages tied to awards here at the Pages for awards link. You must edit these pages to be evaluated for medals and awards, but ultimately the design, layout, style and all other elements of your team wiki is up to you!
Editing your wiki
On this page you can document your project, introduce your team members, document your progress and share your iGEM experience with the rest of the world!
Use WikiTools - Edit in the black menu bar to edit this page
Tips
This wiki will be your team’s first interaction with the rest of the world, so here are a few tips to help you get started:
- State your accomplishments! Tell people what you have achieved from the start.
- Be clear about what you are doing and how you plan to do this.
- You have a global audience! Consider the different backgrounds that your users come from.
- Make sure information is easy to find; nothing should be more than 3 clicks away.
- Avoid using very small fonts and low contrast colors; information should be easy to read.
- Start documenting your project as early as possible; don’t leave anything to the last minute before the Wiki Freeze. For a complete list of deadlines visit the iGEM 2017 calendar
- Have lots of fun!
Inspiration
You can also view other team wikis for inspiration! Here are some examples:
Uploading pictures and files
You can upload your pictures and files to the iGEM 2017 server. Remember to keep all your pictures and files within your team's namespace or at least include your team's name in the file name.
When you upload, set the "Destination Filename" to T--YourOfficialTeamName--NameOfFile.jpg. (If you don't do this, someone else might upload a different file with the same "Destination Filename", and your file would be erased!)
