Usage

Tfad is a terminator sequence derived from the fad gene of C. tetani, encoding FAD-binding oxidreducatse. These enzymes catalyse the conversion of dihydroxyacetone phosphate to glycerol-3-phosphate in a reversible reaction. In our project we use this strong terminator to prevent polar transcription from the pyrKDE operon of C. sporogenes, following chromosomal knock-in of botR in part BBa_K2992025, at this locus. The secondary structure for Tfad was predicted using the Mfold web tool (Zuker, 2003).

Characterisation

This basic part was used upstream of PbotR to prevent chromosomal read-through from the pyrKDE operon, upon integration of the PbotR-botR module. See our results page for more information.
