Hartmut Michel (*1948)
Frankfurt, GER
Biochemist. Fundamental works on channel proteins (ion channels) receptors, and structure-function relations of membrane proteins. Nobel Prize for Chemistry in 1988 for elucidating the threedimensional structure of the photosynthetic reaction center of purple bacteria. In 1982 he succeeded in transforming the photosynthetic reaction center in a crystalline form for X-ray structure analysis.
