lambda promoter (cIts responsive)
This is different from the common lambda promoter in that it is able to be repressed by the temperature sensitive cI protein (BBa_K200011).
This lambda promoter contains 3 operator sites, as opposed to only 2 operator sites on the registry lambda promoter (BBa_R0051)
It has been shown through lysis experiments pL1 that this lambda promoter can be stringently repressed by the cI protein at temperatures up to 30°C. At temperatures higher than 30°C, the cI repressor is progressively thermally denatured and no longer able to bind to the promoter operator regions. Therefore, promoter activity is induced.
The system of the lambda promoter- temperature sensitive cI protein provides an effective way to regulate gene expression using temperature.
Requirements/Limitations
- Possible crosstalk with other lambda repressors
