Pveg-5X leader RNA for Bacillus subtilis
Five leader RNA is ligated to PsacB promoter and spoVG RBS downstream. Different sucrose concentrations can induce the expression of promoters. This device is planned for controlled induction of expression of a large number of proteins in Bacillus subtilis. by ZJU-China 2022.
Usage and Biology
Biology
Pveg is an endogenous strong promoter of Bacillus subtilis, and the leader RNA sequence is from PsacB, which is a endogenous sucrose-sensitive promoter of Bacillus subtilis.The leader RNA sequence contains a terminator overlaping with the binding site of sacY [1] [2]. When the sucrose existed, the sacY can bind to the bing site in the leader RNA and stablized the terminator, which enables the transcription. The absence of sucrose can lead to the formation of terminator structure, which will lead to the early termination of downstream genes.
