Pigments

• Colour: Though E. coli does not naturally produce pigment, several other bacterial species secrete pigmented antibiotics. We have used pigment-producing operons from other bacterial species and transformed them into E. coli. In particular, we have devoted our summer to 3 different pigment systems:

• [Team:Cambridge/Project/CA01 Carotenoids]: The enzymes required for carotenoid production originally come from Pantoea ananatis, and were available in the registry. We used them to produce orange and red.
• [Team:Cambridge/Project/ME01 Melanin]: The tyrosinase required for melanin production originally comes from Rhizobium etli and produces brown.
• [Team:Cambridge/Project/VI01 Violacein]: The enzymes required for voilacein production originally come from Chromobacterium violacein. The operon can be manipulated to produce voilet, green, and blue.
