Improvements

This part is an improved version of https://parts.igem.org/Part:BBa_K562001, originally submitted by team Dundee 2011. The original part contained an illegal XbaI site which has been removed to make it biobrick compatible.

Function:
This part is an improved version of https://parts.igem.org/Part:BBa_K562001, originally submitted by team Dundee 2011. The original part contained an illegal XbaI site which has been removed to make it biobrick compatible. This part has been expressed under different strength promoters. A medium strength Anderson promoter here, low strength Anderson promoter (https://parts.igem.org/Part:BBa_K2213006), and a high strength Anderson promoter (https://parts.igem.org/Part:BBa_K2213008).

The PduD tag was combined with the medium strength Anderson promoter (https://parts.igem.org/Part:BBa_J23108) and mCherry.



A gradient of fluorescence is evident when compared to low and high promoters. When expressed the distribution of the mCherry signal was homogeneous and fluorescence level was slightly less than the high promoter. .




The expression levels compared to low and high are as shown. As the medium strength promoter had similar expression levels to the high promoter, it was not expressed alongside any Eut subunits. This result was unexpected and should be taken into consideration when choosing either the medium or high promoter.
