US Patent 7312049 Total amino acid stabilization during cell-free protein synthesis

Compositions and methods are provided for the enhanced in vitro synthesis of protein molecules, by optimizing the metabolism of amino acids present in the reaction mix, preferably all amino acids in the reaction mixture. By performing synthesis with extracts from genetically modified microbial strains that are deficient in multiple amino acid metabolizing enzymes reduces the enzymatic activities responsible for catalyzing these reactions and improves the overall yield of synthesis.
