Glutathione S-transferase (GST) is a peptide derived from Schistosoma japonicum, in which a target protein may be fused on the N-terminal. This fusion allows the purification of the target protein using glutathione affinity and maximize the presence of the protein in soluble state, rather than on inclusion bodies. In addition, this fusion protein gives stability to other proteins and for this is necessary to use a polyprolyne linker to maintain the original three dimensional structure of the protein.This tag may be later removed by adding a protease recognition site between GST and the target protein (Harper & Speicher, 2013).

Design Notes

GST coding sequence is the one that is use for give structure and stability to Tenascin domain V. The binding is created by a polyproline linker which is going to maintain the original three dimensional structure of the tenascin domain V. GST has a high level of stability because of its structure and we can see it in figure 1. Its structure is mainly composed by alpha-helix structures giving it more stability to it structure. (Chakrabartty and Baldwin, 1995)
