Part:BBa_K4430008
GFP-TSP
It is the key part that is responsible for expressing green fluorescent protein (GFP) fusion protein of tailspike protein (TSP) (GFP-TSP). TSP is from the genome of Salmonella phage P22. The tailspikes of P22 and its podoviral relatives display modular structures. The smaller N-terminal particle-binding domain (PBD) of the homotrimeric TSP binds the elongated molecule to the phage head. This segment of around 110 amino-acid residues is highly conserved in sequence between different phages of the same morphology. The much larger C-terminal part of TSP mediates binding to the receptor (receptor-binding domain, RBD). GFP emits green fluorescence under the confocal laser scanning microscope. Under such microscope, green fluorescence on the cell surface of SE after incubation with GFP-TSP proteins indicates specific binding of the proteins to the bacteria.
