Tar receptor weak expression cassette

Tar receptor is now under the drive of lacI promoter, a constitutive weak promoter. In addition, the Shine-Dalgarno sequence is removed to lower translation efficiency. Lower expression level ensures more specific chemotaxis and better engineering of movement control.

Usage and Biology

pPD10, the empty vector demonstrated no significant chemotaxis while pPD12 vector demonstrated strong chemotaxis. We thus cloned the expression cassette from pPD12 and use it for our chemotaxis experiments.
