Full-length stationary phase osmY promoter

Assembly Compatibility:

We considered different designs for stationary phase regulation of odor production. All designs focused on using transcriptional control devices to regulate the odor enzyme generators and thus odor production. One candidate design for stationary phase regulation was to use a transcriptional promoter that is only active in stationary phase. Several E. coli promoters that are primarily active in stationary phase have been previously characterized Schellhorn-1998, Vijayakumar-2004. Thus, we could evaluate various stationary phase promoters as potential growth phase dependent transcriptional control devices.
