- Yellow enzymes
- A group of respiratory enzymes that catalyze reactions in the body permitting cells to respire, to breath. These biochemical reactions are termed oxidation-reduction reactions. The first yellow enzyme was discovered by the German biochemist Otto Heinrich Warburg (1883-1970), a pioneer in research on the respiration of cells, who won the Nobel Prize in physiology or medicine in 1931 " for his discovery of the nature and mode of action of the respiratory enzyme." All yellow enzymes are flavoproteins (from the Latin flavus, yellow).
* * *any of a number of enzymes having a flavin as a prosthetic group. Historically, NADPH dehydrogenase (occurring in plants and yeast) was called the old yellow enzyme to distinguish it from D-amino acid oxidase, known as the new yellow enzyme. See also flavoprotein.
