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 promotor's express efficiency by measuring the fluorescent intensity of the RFP following the promotor. Different promotors 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.
