Description
This Composite Biobrick is created by standard assembly of Part BBa_K731201 and Part BBa_K274200, which are submitted by previous iGEM teams. The whole cassette is on plasmid pSB1C3 (high copy, Chloramphenicol resistance).
BBa_K274200 contains the enzymes that convert colourless farnesyl pyrophosphate to orange beta-carotene. The carotene operon contains CrtE, CrtB, CrtI and CrtY each one with individual ribosome binding site. This Composite Biobrick has been put under inducible araC-pBAD promoter that is positively regulated by arabinose.
Notes
Standard assembly between BBA_K731201 and a PCR amplification of BBa_K274200.
BBa_K274200 was extracted by the 2012 distribution kit in pSB1A2 and it was amplified by PCR to restore a missing SpEI site.
