Abstract
We present protocols for high-level expression of isotope-labelled proteins in E. coli in cost-effective ways. This includes production of large amounts of unlabeled proteins and 13C-methyl methionine labeling in rich media, where yields of up to a gram of soluble protein per liter of culture are reached. Procedures for uniform isotope labeling of 2H, 13C and 15N using auto-induction or isopropyl-?-D-1-thiogalactopyranoside-induction are described, with primary focus on minimal isotope consumption and high reproducibility of protein expression. These protocols are based on high cell-density fermentation, but the key procedures are easily transferred to shake flask cultures.

Abstract
Recent breakthroughs in isotope-labeling and pulse sequence techniques have enabled the Nuclear Magnetic Resonance (NMR) characterization of large protein systems with molecular weights of hundreds of kDa. NMR studies of a great variety of large proteins have provided unique insights into the binding, dynamic, and allosteric mechanisms. Here we present a brief summary of these...

Until now, a number of methods have been used to study static protein structures, including X-ray crystallography and nuclear magnetic resonance. However, these methods are of no use for proteins that are on the move; analytical methods, computer ...
