High-throughput cell-free systems for synthesis of functionally active proteins

Abstract

Continuous cell-free translation systems with perpetual supply of consumable substrates and removal of reaction products made the process of in vitro synthesis of individual proteins sustainable and productive. Improvements of cell-free reaction mixtures, including new ways for efficient energy generation, had an additional impact on progress in cell-free protein synthesis technology. The requirement for gene-product identification in genomic studies, the development of high-throughput structural proteomics, the need for protein engineering without cell constraints (including the use of unnatural amino acids), and the need to produce cytotoxic, poorly expressed and unstable proteins have caused increased interest in cell-free protein synthesis technologies for molecular biologists, biotechnologists and pharmacologists.
