| 摘要 |
Polypeptides are synthesized in cell-free translation system containing an exogenous RNA-polymerase, DNA molecules as protein genes, nucleic acid and substrates. It contains ATP, GTP, CTP, UTP and amino acids as substrates. During the translation process in the system the following products are synthesized: a specific polypeptide, AMP, GDP, CDP, UDP, pyrophosphate and inorganic phosphate. As the substrates are consumed for the synthesis of the products, the translation products including the specific polypeptide, AMP, GDP, CDP, UDP, pyrophosphate and inorganic phosphate are removed from the system and simultaneously substrates such as ATP, GTP, CTP, UTP and amino acids are delivered to maintain their initial concentration.
