Enhanced yield of recombinant proteins with site-specifically incorporated unnatural amino acids using a cell-free expression system.

Abstract excerpt

Using a commercial protein expression system, we sought the crucial elements and conditions for the expression of proteins with genetically encoded unnatural amino acids. By identifying the most important translational components, we were able to increase suppression efficiency to 55% and to increase mutant protein yields to levels higher than achieved with wild type expression (120%), reaching over 500 µg/mL of...
