FixK2 promoter-rbs-mRFP-term

This biobrick was created by assembling two preexisting biobricks: a gene encoding a mutated version of the red fluorescent protein (BBa_K081014) with rbs and terminator and put under the control of FixK2 (BBa_K592006), a blue light sensitive promoter (465-482nm). FixK2 was previously described by iGEM11_Uppsala-Sweden as working with FixJ.
When FixJ is phosphorylated, it can bind FixK2 and thus activate the downstream system.
In the litterature (Andreas Möglich et al. 2009. Design and Signaling Mechanism of Light-Regulated Histidine Kinases.), FixJ is phosphorylated by YF1 in darkness and unphosphorylated in light. BBa_K592016 is a composite part using YF1 with FixJ.
