Pprovoin5_amilGFP
Pprovoin5_amilGFP
Profile
Name: Pprovoin5_amilGFP
Base Pairs: 976 bp
Origin: Synthetic
Properties: A coding sequence for amilGFP.
Usage and Biology
Ptat_AtzR is a coding sequence for expressing atzR. Cyanuric acid combination with AtzR can activate amilGFP expression to show the signs of fluorescence. The content of cyanuric acid is detected by detecting the fluorescence concentration. So Ptat_AtzR should be used with Pprovoin5_amilGFP.
Construct Design
amilGFP is key functional factors that show the signs of fluorescence which is controlled by a Pprovoin5 promoter (Figure 2). The Pprovoin5_amilGFP is inserted in the pUC57 mini vector to get plasmid A (Figure 3).
The profiles of every basic part are as follows:
BBa_K3995002
Profile
Name: Pprovoin5
Base Pairs: 82bp
Origin: Pseudomonas sp.,genome
Properties: atzDEF/atzR operator
Usage and Biology
This operator region has a leftward-facing repressible promoter and a rightward-facing activated promoter. AtzR remains bound to the DNA. In the natural system, the left-facing promoter is upstream of the atzR CDS, and atzR is autoregulatory; in the presence of cyanuric acid, the binding of AtzR changes to cause the right-facing promoter to become activated, allowing for the expression of the downstream atzDEF CDS. The presence of cyanuric acid "frees" AtzR from being bound to the atzDEF promoter so polymerase can now bind and transcribe following gene. AtzR remains bound to the atzR promoter region even in the presence of cyanuric acid. Note that high glnK concentrations are also needed, as glnK is a co-activator of downstream operator.
