Yeast lytic enzyme is used to digest the cell wall of active yeast cells. Yeast lytic enzyme is an enzyme preparation from a submerged culture of Arthrobacter luteus which effectively lyses cell walls of viable yeast cell. It is a lyophilized enzyme partially purified by affinity chromatography.…

Glucose oxidase is an FAD-containing glycoprotein. The enzyme is specific for β-D-glucose. O can be replaced by hydrogen acceptors such as 2,6-dichlorophenol indophenol. Glucose oxidase from Aspergillus niger is a dimer consisting of 2 equal subunits with a molecular mass of 80 kDa each. Each…

α-Thrombin is a trypsin-like serine protease involved in a multitude of processes in the human body. Thrombin generation is the result of limited proteolysis of the vitamin K-dependent zymogen prothrombin. Thrombin is the last enzyme in the clotting cascade functioning to cleave fibrinogen to…

Streptokinase catalyzes hydrolysis of amide linkages. Forms a 1:1 complex with plasminogen which is then converted to streptokinase-plasmin. Both streptokinase-plasminogen and streptokinase-plasmin complexes can activate plasminogen. As a result of its interaction with human or rabbit plasminogen,…

Catalase occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. It promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells.…

Pyruvate kinase from rabbit muscle is a tetramer consisting of four equal subunits of molecular weight 57 kDa. Pyruvate kinase catalyzes the following reaction: ADP + Phosphoenolpyruvate → Pyruvate + ATP . Both Mg2+ and K+ are required metal cofactors for optimal activity. The enzyme is…
