Design Notes

The Plac/ara-1 is a hybrid promoter which is composed of the activation operator site from the araBAD promoter and repression operator sites from the lacZYA promoter. And the araBAD promoter is placed in its normal location relative to the transcription start site while the lacZYA promoter is placed both upstream and immediately downstream of the transcription start site. In the meanwhile, It can be activated by the AraC protein in the presence of arabinose and repressed by the LacI protein in the absence of isopropyl b-D-1-thiogalactopyranoside (IPTG).
