In Vitro Protein Synthesis of Perdeuterated Proteins for NMR Studies SelectScience
Perdeuteration of polypeptides is a useful technique for studying large polypeptides in solution, however this can be difficult to do in vivo. This application note summarizes work using cell-free synthesis methods employing both H2O-based and 2H2O ...

Abstract
(1) H detection can significantly improve solid-state NMR spectral sensitivity and thereby allows studying more complex proteins. However, the common prerequisite for (1) H detection is the...

Abstract
Cell-free protein synthesis (CFPS) offers a fast and inexpensive approach to selectively label proteins with isotopes that can then be detected by nuclear magnetic resonance (NMR) spectroscopy directly in the translation mixture. We describe...

Suppression of isotope scrambling in cell-free protein synthesis by broadband inhibition of PLP enymes for selective 15N-labelling and production of perdeuterated proteins in H2O
Abstract Selectively isotope labelled protein samples can be prepared in vivo or in vitro from selectively labelled amino acids but, in many cases, metabolic conversions between different amino acids result in isotope scrambling. The best results are obtained by cell-free protein synthesis, where metabolic enzymes are generally less active, but isotope scrambling can never be suppressed completely. We show that...

Journal of Biomolecular NMR; 2007; 39(3); pp 229-238
Abstract:
Cell-free protein synthesis protocols for uniformly deuterated proteins typically yield low, non-uniform deuteration levels. This paper introduces an E. coli cell-extract, D-S30, which enables efficient production of proteins with high deuteration levels for all non-labile hydrogen atom positions. Potential applications of the new protocol may include production of proteins...
