Description
This common lambda promoter is able to be repressed by temperature sensitive cI protein.
This has all 3 operator regions of the lambda promoter, as opposed to only operator region 1 and 2 for the registry promote (BBa_R0051)
This promoter is chosen as it has been shown in bacterial lysis experiments lp1 to be stringently repressed by the temperature sensitive cI protein(BBa_K200011) at temperatures up to 30??C.
At temperatures higher than 30??C, the cI857 repressor is denatured and unable to bind to the promoter. As a result, promoter activity is induced.
The cI protein-lambda promoter pair provide an effective system for temperature sensitive regulation of gene expression.
