GFP is used to report the function of blue light sensor. The LOV photo-switch YF1 was created by fusing the light perception domain of YtvA to the FixL kinase domain. YtvA acts as a blue-light photoreceptor and carries a blue-light-sensitive flavin-binding LOV domain. The response regulator FixJ forms a two-component system together with FixL.
Double terminator consisting of BBa_B0010 and BBa_B0012
Built by Josh as an intermediate in screening plasmid construction.
FixK2 promoter omes from the genome of Bradyrhizobium japonicum.
FixK2 promoter is the wild-type promoter to which phospho-FixJ binds. FixJ in turn can be regulated by YF1, the blue light-sensing protein. This promoter shows very little leaky activity in the absence of FixJ.
The sequence information was provided by Moffat (Moffat et al. 2009). The DNA was synthesized by GenScript.
B0034-YF1-B0034-FixJ, blue light sensor and RR with RBS
The components that made up of YF1 fusion protein comes from Bradyrhizobium japonicum and Bacillus subtilis. FixJ comes from the genome of Bradyrhizobium japonicum.
YF1 works in conjunction with its response regulator, FixJ. This part consists of RBS-coupled YF1 and FixJ without promoter.
This constructs Strong RBS to ensure good expression.
Anderson promoter J23102 without RFP in backbone vector pSB1C3 to easily fuse the promoter with other reporters e.g. the lux operon.
RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.
green fluorescent protein derived from jellyfish Aequeora victoria wild-type GFP (SwissProt: P42212
GFP (mut3b) [note that this part does not have a barcode]
Ytva comes from the genome of Bacillus subtilis. FixL derives from the genome of Bradyrhizobium japonicum.
YF1 is a fusion protein of YtvA (B.subtilis) and FixL(Br.japonicum). It contains the N-terminal region of YtvA (1-127) and C-terminal region of FixL (258-505), interconnected by a helical linker. This fusion protein is designed by Andreas Moglich and Keith Moffat. As shown in previous research, Illumination of the fusion kinase YF1 reduced net kinase activity by ∼1000-fold in vitro. YF1 also controls gene expression in a light-dependent manner in vivo.
The sequence information was provided in Moglich and Moffat's article. The physical DNA was synthesized by GenScript. Codon-optimization may enhance its expression.
FixJ comes from the genome of Bradyrhizobium japonicum.
FixJ comes from the genome of Bradyrhizobium japonicum. It's the wild-type response regulator to YF1, the blue light-sensing fusion protein.
