Design

Special Notes

Designing this part required no modifications. During our design process in DNA 2.0, we ran the sequence through codon optimization and tested the restriction sites, but there were no recommendations that required action. Our inspiration for this project stemmed from reading the literature about possible sources for possible endogenous pathways for the control of bacterial growth. Some papers described quorum sensing pathways, specifically Autoinducer-2, as having metabolic and growth control properties (See reference 1).

Source

The source of the LuxS gene came from UniProt under the name P45578. All other parts were provided through DNA 2.0 under the plasmid name PD441-CH.
