位点特异性重组酶是基础研究和基因工程中极具价值的工具。通过促进高保真的DNA修饰,位点特异性重组系统使研究人员能够对多种生物功能进行前所未有的控制,从而对细胞结构和功能有了无数的深入了解。然而,许多位点特异性重组酶严格的靶标特异性限制了它们在需要高度灵活识别能力的领域中的应用。因此,人们通过蛋白质工程大力致力于改变位点特异性重组系统的特性。在此,我们综述了位点特异性重组酶的合理设计和定向分子进化方面的关键进展,强调了这些酶在不同研究领域的众多应用。
Site-specific recombinases are tremendously valuable tools for basic research and genetic engineering. By promoting high-fidelity DNA modifications, site-specific recombination systems have empowered researchers with unprecedented control over diverse biological functions, enabling countless insights into cellular structure and function. The rigid target specificities of many sites-specific recombinases, however, have limited their adoption in fields that require highly flexible recognition abilities. As a result, intense effort has been directed toward altering the properties of site-specific recombination systems by protein engineering. Here, we review key developments in the rational design and directed molecular evolution of site-specific recombinases, highlighting the numerous applications of these enzymes across diverse fields of study.
