These parts were designed and constructed by the Cambridge 2007 iGEM Team: The original sequences for agrC and agrA were taken from the S. aureus Sequencing Project (results for strain NCTC8325) at Oklahoma University (http://www.genome.ou.edu/staph.html). The sequences were then codon-optimised for E. coli using GeneDesigner from DNA2.0 (http://www.dna20.com), and then synthesised by that company.
S. aureus oligopeptide-based quorum sensing system into a BioBrick-compatible signalling mechanism including the AIP sensor and generator of AIP (auto-inducer peptide).
Used J23107, a mild constitutive promoter, to avoid inserting too many unnatural proteins into the E.coli membrane.
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.
The original sequences for agrB and agrD were taken from the S Aureus Sequencing Project at Oklahoma University (http://www.genome.ou.edu/staph.html). The sequences were then codon-optimised for E. coli using GeneDesigner from DNA2.0 (http://www.dna20.com), and then synthesised by that company.
This part was made in order to transfer the S. aureus oligopeptide-based quorum sensing system into a BioBirck-compatible signalling mechanism. In the natural system, the signalling oligopeptide (termed AIP) is made from AgrD by the membrane-located enzyme AgrB. It is then detected by the membrane-located AgrC, which phosphorylates AgrA which then has DNA-binding activity and upregulates transcription of the promoters termed P2 and P3 in the ''agr'' locus. There are four known variants of AIP with different molecular structures and cross-inhibitory activity; this BioBrick generates group I AIP. This part contains the coding regions for group I agrB and agrD (in that order), prefixed by the B0034 RBS and separated by a SaII site.
Transcriptional terminator consisting of a 64 bp stem-loop.
