构建以稳健和可预测的方式发挥功能的新型生物系统需要更好的方法来发现新的功能分子并优化其在新型生物环境中的组装。通过在缺乏详细机制理解的情况下实现功能多样化和优化,定向进化是对“理性”工程方法的有力补充。在聪明的选择方案的帮助下,定向进化已经为细菌的遗传电路、细胞间通讯系统和非天然代谢途径产生了新的部分。
Constructing novel biological systems that function in a robust and predictable manner requires better methods for discovering new functional molecules and for optimizing their assembly in novel biological contexts. By enabling functional diversification and optimization in the absence of detailed mechanistic understanding, directed evolution is a powerful complement to ‘rational’ engineering approaches. Aided by clever selection schemes, directed evolution has generated new parts for genetic circuits, cell-cell communication systems, and non-natural metabolic pathways in bacteria.
