Highly specific protease
TEV protease (EC 3.4.22.44, Tobacco Etch Virus nuclear-inclusion-a endopeptidase) is a highly sequence-specific cysteine protease from Tobacco Etch Virus (TEV).[1] It is a member of the PA clan of chymotrypsin-like proteases.[2] Due to its high sequence specificity, TEV protease is frequently used for the controlled cleavage of fusion proteins in vitro and in vivo.[3] The consensus sequence recognized by TEV protease is Glu-Asn-Leu-Tyr-Phe-Gln-|-Ser, where "|" denotes cleaved peptide bond.[4]
