Full-length stationary phase osmY promoter

BBa_J45992 is a stationary phase promoter derived from the promoter that controls transcription of osmY in Escherichia coli . BBa_J45992 is active in stationary phase and under high osmotic pressure conditions.

Usage and Biology

Expression of osmY is dependent on σS in vivo . Schellhorn et al. previously demonstrated that an osmY::lacZ fusion generated the highest transcriptional signal in stationary phase as compared to nine other σS-dependent promoter-lacZ fusions . In addition, the osmY::lacZ fusion generated only a small transcriptional signal during exponential growth.
