Design Notes

rrnB P1 is an E.coli constitutive promoter that contains recognition sequences for holoenzymes containing sigma 70. This part was designed and chosen from literature in order to be used for high constitutive expression of a gene. ppGpp at basal levels has been shown to reduce strength of the rrnB P1 promoter.
