Generator

Part:BBa_I746002

Designed by: David Wyatt   Group: iGEM07_Cambridge   (2007-10-23)


AIP generator + mCherry + term

This part is simply the AIP generator (I746000) from the agr system with an mCherry+term device (J06702) downstream.

The original 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 was built to check for transcriptional readthrough - i.e. that I746000 does not contain a cryptic terminator or some other problematic feature. It's also handy for tagging sender cells as red fluorescent (if it works!).
