CrtEBIY under constitutive promoter

This Biobrick is created by putting enzyme cassette CrtEBIY (with individual rbs) of Part BBa_K274200 under constitutive promoter R0011.

Enzyme cassette CrtEBIY (with individual rbs) of Part BBa_K274200 converts colourless farnesyl pyrophosphate to orange beta-carotene (via intermediates geranylgeranyl pyroiphosphate, phytoene and lycopene).

Amount of beta-carotene produced can be measured by photospectrometer with absorbance at 455nm (beta-carotene extraction using acetone).
