ParoF promoter
Part Description
ParoF promoter is a constitutive promoter present in E. Coli which is sensitive to tyrosine and regulated by tyrR protein, it intitiates the synthesis of DAHP (3-deoxy-D-arabino-heptulosonate 7-phosphate synthase) and it is what makes it sensitive to phenylalanine as TyrR & Phenylalanine complex causes inhibition of the transcription of aroF
Usage
Due to its sensitivity to TyrR we use this promoter to regulate the expression of L7Ae under the effect of tyrR and phenylalanine the activity of paroF is optimum for L7Ae expression but in the presence of TyrR and tyrosine the expression of L7Ae is markedly reduced as shown in figure 1.
