 A blueprint for better cholesterol-lowering drugs
Deisenhofer and Istvan found that statins bind to HMGR's active site—the catalytic region of enzymes that binds biological substances—and prevent the enzyme from producing a molecule that is crucial to cholesterol synthesis.
Deisenhofer emphasized that he and his colleagues undertook these studies to learn more about how the cholesterol-synthesis pathway works at the molecular level.
Deisenhofer emphasized, however, that tight binding of statins to the enzyme might not be the whole story.

Johann Deisenhofer recebeu o Prêmio Nóbel de Química de 1988 por ter elucidado a estrutura tridimensional de um centro de reação fotosintética a nível atômico, junto com os Professores Robert Huber e Hartmut Michel, quem também assistirão ao Campus de Excelência.
Deisenhofer chega a Fuerteventura para falar sobre a maneira em que as bactérias (especialmente as gram negativas) transportam ferro por suas membranas.
Deisenhofer afirmou também que muito recentemente, outro grupo de experimentação acaba de descobrir, através de um modelo animal com ratos, que se se removem os genes que controlam a produção destas proteínas que obtêm o ferro em forma de íons, o corpo se volta mais vulnerável às infecções.

 Johann Deisenhofer Biography | Encyclopedia of World Biography
Biochemist and biophysicist Johann Deisenhofer (born 1943) devised a way to use X-ray technology to map the chemical reactions central to plant photosynthesis, earning him the Nobel Prize in Chemistry in 1988.
During the 1980s his work aiding a group of German biologists in studying plant photosynthesis--the process whereby light energy from the sun is converted into the chemical energy that maintains life--resulted in the first-ever mapping of the structure of those molecules involved in the chemical reaction integral to the conversion process.
In 1956, 13-year-old Johann was sent away to a series of boarding schools, and he graduated from Augsburg's Holbein Gymnasium--a gymnasium is the German equivalent of a North American high school--seven years later in 1963.

 HHMI: Nobel Laureates - Johann Deisenhofer
The way plants, algae, and some bacteria harness energy from the sun to produce food is a marvel of biology, and not all the details of the process are well understood.
But between 1982 and 1985, Johann Deisenhofer, working in collaboration with Robert Huber and Hartmut Michel at Germany's Max Planck Institute for Biochemistry, helped resolve the pathway by which sunlight is converted to chemical energy.
Deisenhofer's work has implications far beyond the theoretical understanding of photosynthesis.
