Autoinducer synthase LasI + LVA with combined eforRed chromoprotein expression cassette

This part builds the basis for the construction of an expression cassette of the autoinducer synthase LasI, which synthesizes N-3-oxododecanoyl-homoserine lactone. It is combined with a expression cassette of the chromoprotein eforRed.

Usage and Biology

N-3-oxododecanoyl-HSL binds to the transcription regulator LasR. This complex then binds to specific sequences in the las promoter region activating the expression of genes located downstream. The constitutively expressed chromoprotein eforRed is added to the construct and can be used as a selection marker. Since this contruct does not include a promoter in front of lasI it can be combined with various regulatory regions (e.g. constitutively or regulated promoter) depending on intended use.

-This part is the basis for the expression of the Las auto inducer synthetase, which synthesizes LasI [N-(3-oxododecanoyl)-homoserine lactone]. LasI binds to the activator LasR. Together they activate the Las promoter. A constitutive expression of the chromoprotein eforRed is added to the construct in order to varify the expression of LasI synthetase. The construct has no promoter in front of the LasI synthetase gene. Therefore the user can choose the promoter himself (e.g. constitutive, induced, repressed, etc.)

 ===Usage and Biology===
+N-3-oxododecanoyl-HSL binds to the transcription regulator LasR. This complex then binds to specific sequences in the las promoter region activating the expression of genes located downstream. The constitutively expressed chromoprotein eforRed is added to the construct and can be used as a selection marker. Since this contruct does not include a promoter in front of ''lasI'' it can be combined with various regulatory regions (e.g. constitutively or regulated promoter) depending on intended use.
