MONOPHENOL MONOOXYGENASE Meaning and
Definition
-
Monophenol monooxygenase, also known as tyrosinase, is an enzyme primarily found in plants, animals, and microorganisms, which plays a crucial role in various biological processes. It is responsible for catalyzing the rate-limiting step in melanin biosynthesis, the conversion of tyrosine into dopaquinone.
The enzyme is composed of two copper ions, which are coordinated by three histidine residues in its active site. Monophenol monooxygenase exerts its catalytic action by using molecular oxygen to hydroxylate monophenols and convert them into o-diphenols, which can then be further oxidized to o-quinones. These o-quinones are highly reactive intermediates that participate in a range of reactions leading to the formation of various pigments, such as melanin.
Beyond its involvement in melanin synthesis, monophenol monooxygenase is also implicated in a number of other physiological processes. For instance, it plays a role in the synthesis of neuromelanin, a pigment found in dopaminergic neurons, and is involved in the browning of fruits and vegetables, including the enzymatic browning seen when fruits are cut and exposed to air.
In addition, monophenol monooxygenase has gained importance in industrial applications due to its ability to perform oxidative transformations. It has been widely used in the food industry for the enzymatic browning of certain products, such as coffee and tea. Furthermore, it is utilized in the cosmetic industry for its involvement in skin pigmentation and hair coloration processes.
Overall, monophenol monooxygenase is a biologically and industrially significant enzyme that plays a critical role in melanin biosynthesis and other related

Etymology of MONOPHENOL MONOOXYGENASE
The word "Monophenol Monooxygenase" has a scientific etymology derived from the combination of several roots and suffixes:
1. Mono-: A prefix meaning "one" or "single".
2. Phenol: A compound that is derived from benzene and consists of a hydroxyl group (-OH) attached to an aromatic benzene ring. It is derived from the Greek word "phaino" meaning "to show" or "appear", referring to the common use of phenols in dye production.
3. Mono-oxygenase: A term combining the prefix mono- (meaning "one" or "single") with "oxygenase". Oxygenase is derived from the word "oxygen" and the root "-ase" (indicating an enzyme). In biochemistry, an oxygenase is an enzyme involved in the incorporation of oxygen into organic compounds.
