Biological Activity
Product Information
Produced through fermentation by Aspergillus niger, it remains effective within a pH range of 4.0 to 10.0 and a temperature range of 35°C to 40°C.
Instructions
It can be dissolved using water or as specified in relevant references.
Note: When decomposing hydrogen peroxide, if the concentration of hydrogen peroxide is excessively high (≥1000 mg/L), the reaction rate of the enzyme will decrease.
Catalase, the enzyme that metabolizes H2O2 but also reacts with a multitude of other substrates. The active site of catalase contains an iron atom. Human catalase contains four identical subunits, each subunit containing four distinct domains and one prosthetic heme group. The four domains include: (1) a N-terminal arm which contains a distal histidine, an essential amino acid for the catalase reaction; (2) a β-barrel domain that contains eight β-barrels arranged in an antiparallel fashion with six α-helical insertions, conferring the hydrophobic core of the protein necessary for the tri-dimensional structure of the enzyme; (3) a connection domain which contains the tyrosine residue that binds the heme group; and finally (4) an α-helical domains, which is important for NADPH binding[1].
