Definition of Yellow enzymes

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).
