| − | The HSL receiver RpaR from Rhodopseudomonas palustris (strain ATCC BAA-98 / CGA009) activates expression of GFP protein in response to Coumaroyl-HSL.

| − | When AHL is added with concentration higher than a critical value, the constitutively expressed RpaR will bind to the AHL molecule Coumaroyl-HSL, dimerize and bind to the pRpa regulatory sequence to activate GFP expression.

| − | ==<b>Fluorescent Response to cognate Coumaroyl-HSL</b>==
| + | |
| − | To test this part, we used standard Coumaroyl-HSL (HSL produced by RpaI in P.aeruginosa) to determine the response curve.

| − | It has shown that RpaR is sensitive to it's cognate HSL and has no obvious crosstalk with other HSLs.
