Abscisic-aldehyde Oxidase
In enzymology, an abscisic-aldehyde oxidase () is an enzyme that catalysis, catalyzes the chemical reaction :abscisic aldehyde + H2O + O2 \rightleftharpoons abscisate + H2O2 The 3 substrate (biochemistry), substrates of this enzyme are abscisic aldehyde, water, H2O, and oxygen, O2, whereas its two product (chemistry), products are abscisate and hydrogen peroxide, H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor. The List of enzymes, systematic name of this enzyme class is abscisic-aldehyde:oxygen oxidoreductase. Other names in common use include abscisic aldehyde oxidase, AAO3, AOd, and AOdelta. This enzyme participates in carotenoid biosynthesis. References * * * EC 1.2.3 Enzymes of unknown structure {{1.2-enzyme-stub ...

Enzymology
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ...
