araBAD promoter

The promoter is a part of the arabinose operon whose name derives from the genes it regulates transcription of: araB, araA, and araD. In E. coli, the PBAD promoter is adjacent to the PC promoter, which transcribes the araC gene in the opposite direction. araC encodes the AraC protein, which regulates activity of both the PBAD and PC promoters.

Usage and Biology

Experiment

Figure 1 (a) the pBAD gene of E. coli does include the binding sites of araC plasmid(b)the pBAD gene of E. coli does not include the binding sites of araC plasmid, LacZ alpha gene encodes the β-galactosidase, which could react with ONPG to generate orange color.
