Yellow enzyme, Warburg’s
A key respiratory enzyme discovered by the German biochemist Otto Heinrich Warburg (1883-1970), a pioneer in research on the respiration of cells and the metabolism of tumors. Warburg’s yellow enzyme is a flavoprotein that catalyzes an oxidation-reduction reaction necessary for normal breathing (respiration) , in other words, use of oxygen by cells.
Warburg won the Nobel Prize in physiology or medicine in 1931 “for his discovery of the nature and mode of action of the respiratory enzyme.”

A group of respiratory enzymes that catalyze reactions in the body permitting cells to respire, to breath, or in other word, to use oxygen. These biochemical reactions are termed oxidation-reduction reactions.

- Yellow fever
“This disease was prevalent in the deep south, not just in the seaports. My grandparents lived through an epidemic of yellow jack in central Mississippi around 1900, and they were a long way from the seacoast.”) Today yellow fever is most common in tropical areas of Africa and the Americas. The virus of yellow fever […]
- Yellow fever vaccination
A live attenuated (weakened) viral vaccine for yellow fever. Yellow fever vaccination is recommended for people traveling to or living in the tropical areas in the Americas and Africa where yellow fever occurs. Because yellow fever vaccination is a live vaccine, it should not be given to infants or people with immune-system problems.
- Yellow jack
1) The flag displayed from lazarettos, naval hospitals, and vessels in quarantine. 2) Synonym for yellow fever as, for example, in “…Fernando passed a few weeks recovering from a touch of yellow jack.”
- Yellow jacket sting
A sting from a yellow jacket (or other large stinging insects such as bees, hornets and wasps) can trigger allergic reactions ranging from local responses of limited duration to catastrophic general reactions which can be fatal. The susceptibility to severe reactions appears inherited. Avoidance and prompt treatment are essential. Immediate treatment is with adrenaline by […]
