to stop the e.coli by light, we needed a part that stop the e.coli, and combine this with a light receptor that UCSF made it last year.

"Big" E. coli is easily sorted by FACS !

there was some ways to stop the e.coli running:

Make much more proteins/cell !
-
#making a chemaera with chemotaxis receptor and light sensing receptor
+
-
#stop the motor protein's expression(motB protein: from last year's parts)

-
#controling chemotaxis

etc

-
we chose to control chemotaxis.

We've found out, from the paper(..see refrences), the chemoreceptor that fix the e.coli tumble.

-
it is a fragment of the chemoreceptor "Tsr" (a serin receptor)from aa 290 to 551. we call this tsr-cw(or tsr290).

Concept

Balloonconcept.jpg

The light in the morning leaking from a gap between the curtains... this morning lights calls and awakes the E. coli.

Suprise!!

The E. coli become bigger and bigger like BALLOON!!!

→World first bacteria that swells by lights.!!!

When growing...

The movement of the E. coli can be obvered with the naked eyes !

"Big" E. coli is easily sorted by FACS !

Make much more proteins/cell !

Design

First

The E. coli doesn't have photoreceptor. But...

We have Cph8(utwxas/uCSF;iGEM2005)in our hand

Second

The E. coli divides the cells by forming "partition". So...

'Expression of the enzyme in septem formation is knocked-down.

Third

E. coli rather "extend" due to the action of RodA. So...

We make inducible RodAmut.

Experiments

  1. We made inducible rodAmut.
  2. We made CI inverter and compared it.


Results
