PFixK2-lambda C1-B0034-amilCP blue light sensor output

FixK2 promoter is the downstream signaling promoter of YF1/FixJ blue light-sensing system. The YF1/FixJ system become "inactive" when illuminated by blue light, and "active" in darkness. Needless to say, a system that works in the opposite way with lights activating and darkness inactivating is more desirable. Therefore, an inverter was placed behind FixK2 promoter. When in dark, YF1 becomes phosphorylated and activates FixJ, its own RR. FixJ in turn binds to FixK2 promoter, allowing the transcription of the lambda C1, thus repressing the amilCP output. In light however, YF1/FixJ has no effect on FixK2 promoter, which in turn has near-zero activity. The lambda C1 concentration drops, eventually amilCP will be produced.
