Initial Exercise: Cat, Jonathan, Haydn and Ai
As a 'warm-up' exercise to acquaint the group with molecular biological laboratory techniques, three mini-teams were tasked with creating an interesting GFP fusion. Group A decided that visualing ftsZ in real time, in vivo would be rather cool.\
Ftsz was first identified in a mutant screen in 1980 <ref>(Lutkenhaus, Wolf-Watz and Donachie)</ref> as a gene recquired for bacterial cytokinesis (cell division).
Notes
Primer Design
The plasmid vector we were supplied with contains a strong promoter upstream of a sfGFP coding sequence. Our fusion design relies on amplifying the ftsZ coding region from Bacillus and creating regions of overlap between this and the GFP coding sequence in the plasmid, in order to create the gene fusion.
The desired end product is shown below, with the plasmid in lowercase and the ftsZ coding region insert in upper case.
