comDE Quorum Sensing two component system - native

Quorum sensing two component system with native RBS and Terminator (histidine kinase comD, response regulator comE) of Streptococcus pneumoniae (R6) able to sense the competence stimulating peptide CSP. CSP, a 17 amino acids long 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 [http://www.ncbi.nlm.nih.gov/pubmed/23216914 (Martin et al. 2013)]. BBa_K1351024, BBa_K1351025 are BioBricks containing CEbs form different promoters of S. pneumoniae.

ComE dependent promoters containing bases matching (blue) and differing (red) from the CEbs consensus sequence. (figure modified from [http://www.ncbi.nlm.nih.gov/pubmed/23216914 Martin et al. 2013)]


In contrast to BBa_K1351016 the native RBS was maintained, and no optimized RBS for Bacillus subtilis was added.

This part was generated with the RFC10 standard and has the following prefix and suffix:

prefix with EcoRI, NotI and XbaI: GAATTCGCGGCCGCTTCTAGAG
suffix with SpeI, NotI and PstI: TACTAGTAGCGGCCGCTGCAG

Sites of restriction enzymes generating compatible overhangs have the same color: EcoRI and PstI in blue, NotI in green, XbaI and SpeI in red.
