721-光遗传蛋白进化系统 Optovolution

这份研究介绍了一种名为“光定向进化”（Optovolution）的全新蛋白质工程技术。该方法通过基因改造使酿酒酵母的细胞周期受到特定蛋白质的控制，利用光照作为外部指令来精确调节这些蛋白质的选择压力。研究人员成功培育出了多种新型变体，包括光敏度更高、漏表达更低的转录因子，以及无需补充辅助因子的光遗传学系统。此外，该技术还展现了进化非光敏逻辑门蛋白的能力，证明了其在复杂生物功能设计方面的广泛适用性。这种连续定向进化范式有效地解决了以往难以模拟的动态、多状态及计算型蛋白质特性的工程难题。References:* Gligorovski V, Labagnara M, Scutteri L, et al.
