Quorum sensing two component system (AIP-II sensing histidine kinase agrC, response regulator agrA)

Quorum sensing two component system derived from Staphylococcus aureus N315. This part consists of the AIP-II sensing histidine kinase AgrC and the response regulator AgrA. Upon detection of autoinducing peptide II (AIP-II), AgrC phosphorylates AgrA, which then bindes to distinct binding sites and activates the P2 and P3 promoters. This part should only work for AIP-II. Other AIPs should lead to inhibition.

This part was generated in a modified version of RFC25, where a strong Shine Dalgarno Sequence (SD) is included, and has the following prefix and suffix:

prefix with EcoRI, NotI, XbaI, SD and NgoMIV:	GAATTCGCGGCCGCTTCTAGAGTAAGGAGGAGCCGGC
suffix with AgeI, SpeI, NotI and PstI:	ACCGGTTAATACTAGTAGCGGCCGCTGCAG

Sites of restriction enzymes generating compatible overhangs have the same color:
EcoRI and PstI in blue, NotI in green, XbaI and SpeI in red, NgoMIV and AgeI in orange. Shine-Dalgarno sequence and stop codons are underlined.

This part is used in the 2014 LMU-Munich iGEM project [http://2014.igem.org/Team:LMU-Munich BaKillus].

Luminescence of B. subtilis P_xylA - agrCA / P2-lux and P3-lux was measured in MCSE induced with 0, 0.02, 0.2 % xylose. This plot shows the luminescence readout normalised over OD600 over the course of 6hours. The higher output in xylose induced samples shows the successfull expression of agrCA in B. subtilis.
