We have developed an efficient and novel filter assay method, involving radioactive labelling and imaging, to quantify the expression of soluble proteins from a cell-free translation system. Here this method is combined with the conformational sensitivity of 19F NMR to monitor the folded state of the expressed protein. This report describes the optimisation of 6-fluorotryptophan incorporation in a His-tagged human serum retinol-binding protein (RBP), a disulphide bonded beta-barrel protein. Appropriate reagent concentrations for producing fluorine labelled RBP in a cell-free translation system are described. It is shown that 19F NMR is a suitable method for monitoring the production of correctly folded protein from a high-throughput expression system.
Cell-free expression and stable isotope labelling strategies for membrane proteins
Cell-free expression and stable isotope labelling strategies for membrane proteins
Abstract Membrane proteins are highly underrepresented in the structural data-base and remain one of the most challenging targets for functional and structural elucidation. Their roles in transport and cellular communication, furthermore, often make over-expression toxic to their host, and their hydrophobicity and structural complexity make isolation and reconstitution a complicated task, especially in cases where proteins are targeted to inclusion bodies. The development of cell-free expression systems...

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...
