Description
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.

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.
