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.

Controlling Size

1. Improve Sender
   • 前駆体合成酵素metKを入れてみた．＞結果？
2. Improve Receiver
   • LuxRの感度が良くなるmutation（論文より）を入れてみた．＞結果
3. Localize AHL
