GST

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 the domine of Tenascin V and for this is necessary to use a polyproline 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).
