Introduction | Project Design ( 1.Affinity Tag | 2.Communication Module | 3.Size Control ) | Making Marimos | Our Goal |
Chiba's Project
Our iGEM project is to make a Marimo-ish gathering of bacteria. Marimo is a green spherical shaped algae (shown in Fig.1), which is a popular living organism in Japan as a National Treasure.(<because of its shape?)
Motivation.
(more...)
Design
Our marimo bacteria requres as follows:
|
1.Affinity Tag. Make a His-tagged Flagella. We aimed to stick bacteria by displaying histidines (which bonds each other through metal ions) on the flagellar filament. |
|
2.Communication Module. Make a Bacterial Communication. We make 2 types of cell(sender&receiver) having different gene circuit. Senders sticking each other in advance send a signal to receivers and receivers grow affinity tags. |
|
3.Size Controler. Make an AHL localized region for quorum sensing. |
