Creative Enzymes products

Creative Enzymes - Mouse Prothrombin

Prothrombin is a vitamin K-dependent plasma protein which is synthesized in the liver. Prior to secretion into plasma, prothrombin undergoes post-translational modification by a vitamin K-dependent carboxylase which converts ten specific glutamic acid residues to γ-carboxyglutamic acid (gla).

Creative Enzymes - Bovine Plasminogen

Purified from freshly collected bovine plasma. The protein purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol. No Plasmin activity is detected using chromogenic substrate S-2251. Plasminogen is activated to the serine protease plasmin via urokinase, streptokinase or tissue plasminogen activator.

Creative Enzymes - Human Prekallikrein

Purified from fresh frozen human plasma. Human Prekallikrein is a single chain gamma globulin glycoprotein that participates in the early phase of contract activation, kinin formation and fibrinolysis. Prekallikrein purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol. Activity is determined via clotting assay.

Enzymes- Chemical Processing

Creative - Native Aspergillus sp. Lipase (API)

This product is a lipase (TLL) from Thermomyces lanuginosus and it is produced by a submerged fermentation of Aspergillus sp. In opposition to most enzymes, lipases exhibit a wide specificity, recognizing very different substrates. This permits to use a determined lipases as a catalyst for very different reactions, and makes that lipases may be used in pharmaceuticals and drugs production, in energy (biodiesel) or food manufacture, etc. TLL enzyme is a basophilic and noticeably thermostable enzyme. Initially oriented toward the food industry, TLL has been used in many different industrial areas such as modification of fats and oils, production of biodiesel, production of fine chemicals (mainly in enatio/regioselective or specific processes), etc. This product is optimally designed for production of API.

Medical Enzymes - Digestive Enzymes

Creative Enzymes - Native Chymotrypsin

Chymotrypsin is a digestive enzyme component of pancreatic juice acting in the duodenum where it performs proteolysis, the breakdown of proteins and polypeptides. Chymotrypsin preferentially cleaves peptide amide bonds where the carboxyl side of the amide bond (the P1 position) is a large hydrophobic amino acid (tyrosine, tryptophan, and phenylalanine). These amino acids contain an aromatic ring in their sidechain that fits into a `hydrophobic pocket` (the S1 position) of the enzyme. It is activated in the presence of trypsin.
