Protein structure determined in living cells
The function of a protein is determined both by its structure and by its interaction partners in the cell. Until now, proteins had to be isolated for analyzing them. An international team of researchers from Tokyo Metropolitan University, Goethe University, and the Frankfurt Institute for Advanced Studies (FIAS) has, for the first time, determined the structure of a protein in its natural environment, the living cell. Using nuclear magnetic resonance (NMR) spectroscopy, the researchers solved the structure of a protein within the bacterium Escherichia coli. "We have reached an important goal of molecular biology", says Prof. Peter Güntert from the Goethe University's Biomolecular Magnetic Resonance Center. (BMRZ) of The research results will be published by the scientific journal Nature on March 5, 2009.
