Design Notes
Initially, our plasmid's RBS component, synthesized by Genscript, had an unwanted point mutation. But we did characterization to see whether it could still function well (Figure 2).
Source
The leucine-responsive regulatory protein Lrp was constitutively expressed as driven by J23101. Then, Lrp activates the expression of cI repressor in the presence of butyrate, and the cI protein inhibits promoter pLam activity (Figure 1). The pCI-Lam, PpchA, protein CI, and GFP were synthesized by Genscript. The Lrp protein was supported by NMU-China.
