Description
This part is designed to detect the presence of botulism toxin type C. It is composed of a ribosome binding site, a fluorescent protein (SBFP2), a cleavage site that the toxin attacks (Syntaxin-1A), and a 10x his-tag. Ideally, this should be able to be purified after production using a nickel or copper column, eluted, and then mixed with the sample. If the toxin is in solution, it will cleave the Syntaxin-1A sequence, separating the fluorescent protein from the his-tag. This means that if the solution is run through a column again, the fluorescent protein should come out during the flow throughs rather than the elutions.
Notes
Syntaxin-1A is from humans, eukaryotic organisms, so it may not work with E. coli. A blue fluorescent protein was chosen because this part is part of a set for a class project and will be different from GFP and RFP that will be released by different strains of botulism toxin.
