Tar receptor under the control of constitutive promoter J23100

The transmembrane chemoreceptor Tar of E. coli mediates chemotaxis towards aspartate and exists as a functional homodimer.

Here we used a set of 8 constitutive Anderson promoters from the 2006 Berkeley group to test how different levels of constitutive Tar expression affect the chemotaxis of E. coli.
