<p>Enterokinase (EK) is a duodenal protease involved in digestion by activating trypsinogen into trypsin, which in turn activates other pancreatic enzymes. EK specifically cleaves after the sequence Asp-Asp-Asp-Asp-Lys (DDDDK↓) and is inactive if a proline follows the site.<br>Recombinant bovine enterokinase (rbEK) shows higher activity than EK from other species and is widely used in biochemical applications. It is a glycosylated single-chain protein of ~200 amino acids, tagged with C-terminal 6×His for Ni²⁺ affinity purification and easy removal after digestion. The purified rbEK has a molecular weight of ~40 kDa and is fully biologically active.</p>

<p>SUMO protease, also known as Ulp, is a highly specific enzyme that removes small ubiquitin-like modifier (SUMO) from recombinant SUMO fusion proteins. Unlike proteases such as enterokinase or TEV, which recognize linear amino acid sequences, SUMO protease recognizes the native tertiary structure of SUMO, allowing precise cleavage without leaving extra residues at the cleavage site.<br><br>This recombinant SUMO protease is derived from Saccharomyces cerevisiae, expressed in E. coli, and purified to obtain high yields of active enzyme under animal-free conditions. It is well suited for applications in drug and vaccine development, protein manufacturing, and other research uses. A C-terminal 6×His tag is included to enable easy removal of the protease following cleavage via Ni²⁺ affinity purification.</p>

<p>Enterokinase (EK) is a serine protease produced in the duodenum and involved in mammalian digestion. It activates trypsinogen to trypsin, thereby indirectly initiating the activation of pancreatic digestive enzymes. EK specifically cleaves after the recognition sequence Asp-Asp-Asp-Asp-Lys, but is inactive if a proline follows the cleavage site.<br>This recombinant bovine enterokinase is the light chain catalytic subunit, comprising a single glycosylated polypeptide chain corresponding to residues Ile801–His1035 of the native protein (Accession # P98072). Expressed in Pichia pastoris under animal-free conditions, the enzyme is highly active and suitable for applications in drug and vaccine development. A C-terminal 6×His tag is included to allow efficient removal by Ni²⁺ affinity chromatography following cleavage reactions.</p>

<p>Tobacco Etch Virus (TEV) protease is a highly site-specific cysteine protease commonly used to remove affinity tags from fusion proteins. It recognizes the sequence Glu-Asn-Leu-Tyr-Phe-Gln↓Gly/Ser (ENLYFQ↓G/S), with cleavage occurring between the Gln and Gly or Ser residue. The most frequently used recognition site is ENLYFQG.<br><br>The optimal cleavage temperature is 30 °C, though conditions such as enzyme amount, incubation time, and temperature may require optimization for different substrates. TEV protease includes an N-terminal 6×His tag, allowing for convenient removal after digestion via Ni²⁺ affinity chromatography.<br><br>The recombinant enzyme consists of 231 amino acids, has a molecular mass of approximately 28.4 kDa, and is fully biologically active following purification.</p>
