XylS Main Page-BBa_K1031911 XylS is a σ70-dependent transcriptional factor that activates Pm promoter when benzoate acid or its derivative is present. We exploited it to build a XylS biosensor circuit. Adaptor for this biosensor will improve the detection performance of XylS. Visit Wiki
HbpR Main Page-BBa_K1031300 HbpR is a σ54-dependent transcriptional factor, which activates PC promoter when 2-hydroxybiphenol or 2-aminobiphenol is exist. We built a HbpR biosensor circuit and fine-tuned it, making it work in E.coli. Visit Wiki
NahF Main Page-BBa_K1031620 NahF is the salicylaldehyde dehydrogenase to transform salicylaldehyde into salicylic acid (salicylate) using NAD+. We tested NahF in E.coli and showed that the NahF can work as an adaptor for biosensor NahR, meaning that NahF notably improve the performance and range of detection. Visit Wiki
Hybrid Promoter Main Page-BBa_K1031021 The hybrid promoter is constructed for the band-pass filter. As for the reporter node, a special promoter is used so that the reporter can be controlled by the activator and inhibitor at the same time. Promoter engineering was performed to serve the purpose. Additionally, we tested this hybrid promoter and constructed a model for it. Visit Wiki
NahR Main Page-BBa_K1031610 Pre-existing Part: Main Page-BBa_J61051 BBa_K1031610 is upgraded from previous part BBa_J61051 designed by Arkin Lab. NahR is a 34 kDa transcription factor mined from Pseudomonas putida which binds to nah and sal promoters to activate transcription in response to the inducer salicylate. We constructed a Psal/NahR biosensor circuit using sfGFP as reporter gene and systematically characterized its performance . Adaptor of this biosensor not only improves detection efficiency but also expands detection profile. Visit Wiki

Figure 1. The aromatics spectrum showing the aromatics-sensing profiles of our individual biosensors. Each color segment in the central spectrum represents the detection profile of a biosensor. Structural formula highlighted in color stand for the aromatic compounds that can be detected by our biosensors.┝ stand for Adaptors, enzymes that convert undetectable compounds into detectable aromatics, thus to expand the detection capacity of some biosensors.

Figure 2. Experimental points and the linear fitting curves of the orthogonality test. The black dashed lines are with the slopes of 1, showing as the reference line. The slopes of the experimental fitting curves were showed in the upside portion of the figure, all of them were around 1. These data showed the orthogonality among inducers of biosensors(a, b) XylS and NahR; (c, d) XylS and HbpR; (e, f) NahR and HbpR, (g, h) XylS and DmpR, (i, j) NahR and DmpR, and (k, l) HbpR and DmpR. The experimental points and linear fitting curves of biosensor and its inducers are marked in different colors: XylS in red, NahR in green, HbpR in orange and DmpR in dark cyan.(For more details, please Click Here)
