Abstract
We report a general method for amino acid-type specific 17 O-labeling of recombinant proteins in Escherichia coli. In particular, we have prepared several [1-13 C,17 O]-labeled yeast ubiquitin (Ub) samples including Ub-[1-13 C,17 O]Gly, Ub-[1-13 C,17 O]Tyr, and Ub-[1-13 C,17 O]Phe using the auxotrophic E. coli strain DL39 GlyA λDE3 (aspC- tyrB- ilvE- glyA- λDE3). We have also produced Ub-[η-17 O]Tyr, in which the phenolic group of Tyr59 is 17 O-labeled. We show for the first time that 17 O NMR signals from protein terminal residues and side chains can be readily detected in aqueous solution. We also reported solid-state 17 O NMR spectra for Ub-[1-13 C,17 O]Tyr and Ub-[1-13 C,17 O]Phe obtained at an ultrahigh magnetic field, 35.2 T (1.5 GHz for 1 H). This work represents a significant advance in the field of 17 O NMR studies of proteins.

Abstract
17 O NMR spectroscopy has been the subject of vivid interest in recent years, because there is increasing evidence that it can provide unique insight into the structure and reactivity of many molecules and materials. However, due to the very poor natural abundance of oxygen-17, 17 O labeling is generally a prerequisite. This is a real obstacle for most research groups, because of the high costs and/or strong experimental constraints of the most frequently used 17 O-labeling schemes. Here, we show for the first time that mechanosynthesis offers unique opportunities for enriching in 17 O a variety of organic and inorganic precursors of synthetic interest. The protocols are fast, user-friendly, and low-cost, which makes them highly attractive for a broad research community, and their suitability for 17 O solid-state NMR applications is demonstrated.
