To understand the behavior of proteins under intracellular crowding conditions, it is indispensable to observe their three-dimensional (3D) structures at the atomic level in a physiologically natural environment. We demonstrate the first de novo protein structure determinations in eukaryotes with the sf9 cell/baculovirus system using NMR data from living cells exclusively. The method was applied to five proteins, rat calmodulin, human HRas, human ubiquitin, T. thermophilus HB8 TTHA1718, and Streptococcus protein G B1 domain. In all cases, we could obtain structural information from well-resolved in-cell 3D nuclear Overhauser effect spectroscopy (NOESY) data, suggesting that our method can be a standard tool for protein structure determinations in living eukaryotic cells. For three proteins, we achieved well-converged 3D structures. Among these, the in-cell structure of protein G B1 domain was most accurately determined, demonstrating that a helix-loop region is tilted away from a beta-sheet compared to the conformation in diluted solution.
