Part:BBa_I746100

AIP sensor infrastructure (agrC + agrA from S. aureus with RBSes)

This part was made in order to transfer the S. aureus oligopeptide-based quorum sensing system into a BioBrick-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 agrC and agrA (in that order) from S. aureus strain NCTC8325, prefixed by the B0034 RBS and separated by a BamHI site.
