摘要

我们利用人工智能驱动的从头蛋白质设计，创造出新一代荧光素酶催化剂（称为 neoLux 系列），与原生荧光素酶相比，它们具有更优越的特性。这些特性包括体积小巧、稳定性强、不依赖于辅助因子、细胞表达效率高、催化效率高以及独特的底物正交性，标志着超越原生荧光素酶限制的重大进步。此外，我们通过计算设计了高效的新荧光蛋白佛斯特共振能量转移（FRET）融合体，能够在细胞内和体内同时进行多参数成像。我们的开创性方法创建了一个统一的发光工具包，可在体内对癌症异质性进行多色追踪，为复杂的生物学发现铺平了道路。

De novo luciferases enable multiplexed bioluminescence imaging

We leverage AI-powered de novo protein design to create a new generation of luciferase catalysts, termed the neoLux series, which exhibit superior properties over native luciferases. These features include compact size, robust stability, cofactor independence, efficient cellular expression, higher catalytic efficiency, and unique substrate orthogonality, marking a significant advancement beyond the limitations of native luciferases. Additionally, we computationally designed highly efficient neoLux-fluorescent protein Förster resonance energy transfer (FRET) fusions capable of simultaneous multi-parametric imaging in cellulo and in vivo. Our pioneering approach has created a unified luminescent toolkit to allow for multi-colored tracking of cancer heterogeneity in vivo, paving the way for complex biological discovery.
