EC 1.11.1.6 • Mr ca. 240 000 • CAS [9001-05-2]
Catalase is used for the removal of peroxides, the generation of oxygen and, in coupled systems, for the determination of metabolites e.g., uric acid (1). The enzyme preparation is homogeneous in SDS-PAGE.
Activity: ca. 40 000 U/mg protein. Isoelectric point: 5.4
Unit definition: 1 U catalyzes the cleavage of 1 µmole hydrogen peroxide per minute to water and oxygen at 25 °C, pH 7.0. The decrease in hydrogen peroxide concentration can be followed spectrophotometrically at 240 nm (1).
