Laureates of the Nobel Prize in Chemistry. Mitchell Herbert C. Ernst Rudolph A. Barry Sharpless John B. Yonath Richard F. The refinement of these structures was finished in In the following two years he worked on several projects in Robert Huber's lab: human C3a, citrate synthase and alphaproteinase inhibitor.

InHartmut Michel reported in one of Huber's group seminars his spectacular success with the crystallization of the photosynthetic reaction centre from Rhodopseudomonas viridis. Deisenhofer joined the reaction centre project in order to determine the three-dimensional structure of this molecule. Other collaborators were Kunio Miki and Otto Epp. It still took almost three years to work out the complete structure, and two more years to refine the model at 2.

Bragg W. Bragg B. Brockhouse Prince L. Deisenhofer later recalled of his experience in the award-winning project in his autobiography for the Nobel e-Museum: "It was a special privilege to belong to the very small group of people who saw the structural model of this molecule grow on the screen of a computer workstation, and it is hard to describe the excitement I felt during this period of the work.

In addition to paving the way for the creation of artificial photosynthetic reaction centers, their findings were acknowledged for their potential as tools to gain knowledge about other biologic functions, such as the function of cell hormones, respiration, nutrition, and nerve impulses. The Nobel Prize changed Deisenhofer's world. Instead of working quietly in his laboratory in Germany, he was now a celebrity of sorts, and he and his award-winning colleagues were asked to present papers and appear at a host of science-related functions.

A fellow of the American Association for the Advancement of Science since and named an Argonne johann deisenhofer autobiography meaning inDeisenhofer also belongs to the American Crystallographic Association, the German and U. National Academy of Sciences since After moving to the United States and establishing a permanent residence in this country, Deisenhofer applied for and was granted dual U.

In addition to his role as Regental Professor and professor of biology at UTSMC he also accepted a position as an investigator at the Dallas unit of the Howard Hughes Medical Institute, where he is able to promote the use of X-ray crystallography in the study of water-soluble proteins, membrane proteins, and other macromolecules and develop additional crystallographic software.

Early in his tenure at the Texas research center he also met the woman who would become his wife, microbiology professor and fellow Howard Hughes Medical Institute investigator Kirsten Fischer Lindahl. Deisenhofer and Lindahl were married in and continue to make their home near Dallas, Texas. Although Deisenhofer has a reputation for being shy and totally involved in his work, he also finds time to enjoy music and chess, swimming and skiing, and is an amateur history buff.

As an outgrowth of his lab work, in he joined fellow scientist James R. Norris of the Argonne National Laboratory in writing the two-volume book The Photosynthetic Reaction Center, based on research emanating from his Nobel Prize-winning investigation into photosynthesis. Among his continuing goals as a scientist is the ability to discover the rules defining the three-dimensional structure of proteins.

By learning this, the biophysicist reasons, scientists will be a good deal closer to understanding the basic structural component of all life on Earth.

Deisenhofer contributed to the understanding of photosynthesis, the transformation of sunlight into energy in plants. Using x-ray crystallography and advanced mathematical calculations to interpret the x-ray pattern, Deisenhofer, Huber, and Michel detailed the complete atomic structure of the photosynthetic reaction center. Their work provided new insight into the process of photosynthesis and revitalized its study.
