comDE Quorum Sensing two component system (Freiburg Standard)

Quorum sensing two component system (histidine kinase comD, response regulator comE) of Streptococcus pneumoniae (R6) able to sense the competence stimulating peptide CSP.

CSP, a peptide pheromone, binds to and consequently activates the membrane-embedded sensor kinase ComD by changing the conformation of the polytopic kinase. ComD autophosphorylates and subsequently transphosphorylates the cognate response regulator ComE. ComE acts as transcription activator via binding to -10 promoters regions of early and late competence genes. These ComE binding sites (CEbs) consist of a 9 bp direct repeat separated by a stretch of 12 nucleotides.

This part contains optimized RBS for Bacillus subtilis and 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: GAATTCCGCGGCCGCTTCTAGATAAGGAGGAGCCGGC
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.
