EsaR D91G mutant

A variant of the Quorum Sensing regulator protein EsaR BBa_K2116001 with the Aspartic acid substituted by Glycine.

Characterisation

According to the literature[1], the amino acid substitution has increased the sensitivity of this protein to 3OC6HSL molecule. The result of our characterisation is shown below and more details can be found in part <a href="https://parts.igem.org/Part:BBa_K3989003"> BBa_K3989003 </a>.
