araBp

This part is used as an inducible promoter sensitive to varying concentrations of L-Arabinose. araBAD promoter is repressed by the presence of glucose and can be used to regulate gene expression.

Usage and Biology

Biology

The araBAD promoter of the L-Arabinose operon in Escherichia coli allows tightly controlled, titrable expression of the gene of interest placed downstream the promoter. The promoter is sensitive to small changes in the concentration of arabinose while glucose serves as a repressor. The araBAD promotes has Pc subunit, O1 subunit, CAP binding subunit, I1 + I2 subunit and pBAD promoter region.

Usage

We are using this promoter for the production of ccdB L83S mutant protein <a href="https://example.com">Website</a> by induction with arabinose.
