Promoter xyl and RBS spoVG for B subtilis

Details

• Types: DnaRegion
• Roles: engineered_region; Generator
• Sequences: BBa_K143057_sequence (Version 1)

Description

Inducible promoter xyl(BBa_K143014) coupled to the strong Ribosome Binding Site spoVG(BBa_K143021) from B. subtilis.

Pxyl-spoVG can be used to take an input of xylose and give a Ribosomes per second (RiPS) output generator.

Xylose does not directly induce the expression of the promoter xyl, but requires the transcriptional regulator XylR, (BBa_K143036). This means that XylR must be constitutively expressed in B.subtilis in order to use the promoter hyper-spank as an inducible promoter. XylR is naturally expressed by B. subtilis but should be upregulated to increase efficiency.

To get the highest level of translation from this Promoter-RBS combination it must be connected to a coding region preceded by a coding region prefix1. A standard prefix will increase the distance between the RBS and the start codon, reducing translational efficiency.

Notes

The sequence of promoter xyl and RBS-spoVG were obtained from papers1 2 3 and the sequence synthesised by GeneArt
