rhamnose-inducible rhaBAD promoter + kaiABC Operon

The following composite parts contains the cyanobacterial circadian oscillator core genes, expressed in an operon driven by the rhamnose-inducible rhaBAD promoter (PrhaBAD) [1]. The core circadian clock of the cyanobacterium Synechococcus elongatus PCC 7942 is composed of three components, KaiA, KaiB, and KaiC, expressed as monocistronic kaiA and dicistronic kaiBC transcripts. The kaiBC operon is upregulated by the KaiA protein and downregulated by the KaiC protein to generate a circadian oscillator. KaiB can bind to KaiA, therefore opposing KaiA’s stimulatory activity by sequestering it, and to KaiC, driving the KaiC phosphorylation cycle in a clockwise direction.
