P1 promoter
Usage and Biology:
This promoter comes from a kit which contains combinations of specific constitutive bacterial promoters that vary in strength.
Design:
We have chosen a series of constitutive promoters with different strength which include P1. They are used to reliably drive expression of CaAP and McbABCEFG in E. coli in a controlled, reliable manner. We have tested these different, unique combinations to find the best expression level of CaAP and McbABCEFG.
Characterization:
We characterized the promoter's express efficiency by measuring the fluorescent intensity of the RFP following the promoter. The bacteria are incubated under two different conditions. Different promoters had varied features of expression.
Further Application:
This part comes from a collection of precisely quantitated bacterial transcription and translation initiation elements. You can directly choose a promoter with suitable strength to drive expression of a gene of interest in E. coli from those we have tested. You can also combine them with other elements to achieve your goal.
