How to solve
Plasmid construction-1 RBS MT Cd p
Catching E.coli has two merits
Cd² ⁺ Cd² ⁺ Cd² ⁺ Catching E. coli is not weaken or is killed by absorbed cadmium. Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺
Recyclable system of cadmium Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺
We have constructed fusion protein RBS MT Cd p
But we have problems
E. coli may escape from cadmium by negative chemotaxis.
Thanks for
Modeling by UT-Tokyo
Swarming assay E. coli E. coli E. coli go away from cadmium!!! Cd ddH2O
If use only catching E. coli
How to solve? Gathering to cadmium ion → Positive chemotaxis Positive chemotaxis factor → Aspartic acid(Asp)
Go to Asp?
E. coli Asp_concentration
E. coli go to Asp!!!
Using AspA OM IM fumafic acid aspartic acid ammonium ion RBS AspA Cd p
Aspartic acid synthesis by Gathering E. coli − Cd 2+ + Cd 2+ 1 50 1 200 1 100 1 100 1 50 1
Overview
protease ClpXP Protease: ClpAP Digested!! AspA LVA tag
Remove LVA tag AspA LVA tag BBa_C0083
