Lysine riboswitch

Description

Riboswitches are metabolite-sensitive elements found in mRNAs that control gene expression through a regulatory secondary structural switch.RS is a Lysine riboswitch that Regulated by lysine. The following is the control principle diagram

Result

We put the lysine riboswitch connected sfGFP engineered bacteria in different concentrations of lysine for 24 hours, and then tested the fluorescent expression of the bacteria. The results are shown in the following.

Relationship between Lysine Concentration and Fluorescence Intensity in Lysine Riboswitch

The results show that the bacteria are in the lysine at a concentration of 30μmol/mL. Fluorescence expression was significantly inhibited, indicating that the lysine riboswitch can work normally.
