Removal of affinity purification tags such as maltose-binding protein (MBP) or poly-histidine from fusion proteins Optimal activity and stability for up to 24 months The optimum recognition site for this enzyme is the sequence Glu-Asn-Leu-Tyr-Phe-Gln- (Gly/Ser) [ENLYFQ (G/S)] and cleavage occurs between the Gln and Gly/Ser residues, The most commonly used sequence is ENLYFQG. Mol Ther Nucleic Acids. One point to consider is whether the tag is fused to the N- or C-terminal. I usually remove samples at various time-points and analyze them by SDS- PAGE. ENLYFQS , TEV protease . We all love to purify proteins that have some kind of tag on it (I am talking about those of us who work with recombinant proteins). In general, you want one that cleaves efficiently at low temperatures and in different ionic conditions.
