Nitrogenase is an enzyme responsible for catalyzing nitrogen fixation, which is the reduction of nitrogen (N 2) to ammonia (NH 3) and a process vital to sustaining life on Earth. [9] There are three types of nitrogenase found in various nitrogen-fixing bacteria: molybdenum (Mo) nitrogenase, vanadium (V) nitrogenase , and iron-only (Fe ...
Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...
Cofactors can be either inorganic (e.g., metal ions and iron-sulfur clusters) or organic compounds, (e.g., [Flavin group|flavin] and heme). Organic cofactors can be either prosthetic groups, which are tightly bound to an enzyme, or coenzymes, which are released from the enzyme's active site during the reaction.
An example of an enzyme that contains a cofactor is carbonic anhydrase, which uses a zinc cofactor bound as part of its active site. [60] These tightly bound ions or molecules are usually found in the active site and are involved in catalysis. [1]: 8.1.1 For example, flavin and heme cofactors are often involved in redox reactions.

Can inactivate certain enzymes, as a result, both the metal and some compounds (especially methylmercury) are harmful to most life forms; there is a long and complex history of mercury poisoning in humans. [11] molybdenum: 42: 5: Found in many enzymes; essential to all eukaryotes, and to some bacteria.
For example, carbon-containing compounds such as alkanes (e.g. methane CH 4) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as halides of carbon without carbon-hydrogen and carbon-carbon bonds (e.g. carbon tetrachloride CCl 4), and certain compounds of carbon with nitrogen and ...
Enzymes appear in the subcategory Category:Enzymes by function according to the EC number classification: . EC 1 Oxidoreductases: catalyze oxidation/reduction reactions; EC 2 Transferases: transfer a functional group (e.g. a methyl or phosphate group)
In this way, the two substrates of this enzyme are an amide and H 2 O, whereas its two products are monocarboxylate and NH 3. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is acylamide amidohydrolase.
