J23117-Bc345


Tandem rioswitches bc345 are located in the promoter J23117 upstream. It can control gene expression. There are low leakage expression of gene which you interest in E.coli whose concentration of c-di-GMP is in a normal level. When cell is induced expression gene which can catalyze c-di-GMP from GTP, the tandem riboswitches would trans to open form and express its downstream gene.

(a)Comparison of Bc3, Bc4, Bc5 terminators. Red rectangle shows the GC rich region of three terminators, respectively. (b) Secondary structure comparisons of Bc3, Bc4 and Bc5 aptamers with Vc2 aptamer. Conserved motifs such as tetra-loop (blue motif in stem P2), tetra-loop receptor (green motif in stem P3) and G·C base pair (C base in stem P2 and G base in stem P3 were drawn in magenta) connecting P2 with P3 were all colored to facilitate comparison. c-di-GMP was drawn in cyan and its interacting bases drawn in red.(Zhou et al., 2016) (c) Multiply local sequence blast of riboswitches’ terminators. Blue rectangle shows U region of riboswitches.
