PcotV: B. subtilis promoter regulates spore crust protein cotV
The promoter PcotV lies within cotVWXYZ gene cluster, which regulates expression of CotV. The protein CotV is a componend of the spore crust. Therefore, PcotV is activated in late sporulation.
Usage and Biology
|
We used this promoter for the expression of spore crust fusion proteins.
Evaluation
We compared this BioBrick with other promoters that are involved in spore crust formation such as PcotYZ and PcgeA. To test the activity we cloned this promoter into the lux-reporter vector pSBBS3C-luxABCDE (BBa_K823025) and measured the luminescence.
The results of the luminescence measurements are shown in the following figure, which also shows the activities of the related promoters PcotV (BBa_K823033) and PcgeA.
|
This part was used to display fusion proteins on B. subtilis spores with BBa_K823049.
