TEV Protease is the 241 amino acid, 27 kDa catalytic domain of the nuclear inclusion a （NIa） protease from tobacco etch virus. As a 3C-type protease, this enzyme specifically recognizes and processes at the consensus sequence Glu-Asn-Leu-Tyr-Phe-Gln-Gly in cis and in trans, and cleavage occurs between the Gln and Gly residues. Unlike factor Xa, enteropeptidase or thrombin, has not been found to cleave at unintended sites even when present at high concentration. Due to its high specificity and high activity rate within a wide range of pH and ionic strength conditions, is an optimal and useful reagent for removing affinity tags from genetically engineered fusion proteins. However, a serious drawback of is its autocatalytic activity at S2256 to generate a truncated enzyme with greatly diminished activity. Therefore, mutated s have been produced for improved stability.
