Our aim is to introduce a system capable of producing lutein from carotenoid precursors into a bacterial system. As these pathways are native to plants and nonexistent in bacteria, tne main challenge is obtaining every enzyme necessary to allow the pathway to occur. Strains of lycopene (a carotenoid precursor) producing bacteria already exist, and we expect to begin the synthesis from this point. Another main challenge is the regulation of genes required to proceed from lycopene to lutein. Lycopene is the precursor for a multitude of carotenoids, all of which are produced in pants due to necessity. To produce lutein, the lycopene must first undergo a reaction with the specific enzymes in order, ε-cyclase then β-cyclase. Having both enzymes in the system, though, allows reactions between β-cyclase and lycopene, which yields a product unable to be converted into lutein. Through regulatory measures such as altering gene expression levels, we plan to optimize the efficiency of the lutein synthesis pathway. We also aim to create a mathematical modeling system capable of correlating the expression levels of proteins to relevant efficiencies in similar synthesis pathways.

Antibiotic resistance is a necessary selection factor for transgenic bacteria using plasmids as vectors. This staple of genetic engineering has been met with opposition with valid claims that the addition of antibiotics to the environment harms native species and poses a risk to unwanted antibiotic resistance through lateral gene transfer.
