荧光蛋白 (FP) 的多样化生化和光物理特性使得能够产生越来越多的颜色,为其在各种现代生物学应用中的使用提供了独特的机会。这些 FP 特征的调节是通过发色团结构以及发色团与周围蛋白质桶之间接触的多样性来实现的。在这里,我们回顾了目前关于永久发射 FP、光激活 FP 和荧光计时器中蓝色、绿色和红色发色团形成的知识。对 FP 结构和功能之间相互作用的理解的进展使得 FP 的工程具有许多理想的特性,并使得显微镜技术取得了最新进展,例如单分子超分辨率成像、蛋白质动力学成像、光致变色 FRET、深层组织成像和活体动物的多色双光子显微镜。
The diverse biochemical and photophysical properties of fluorescent proteins (FPs) have enabled the generation of a growing palette of colors, providing unique opportunities for their use in a variety of modern biology applications. Modulation of these FP characteristics is achieved through diversity in both the structure of the chromophore as well as the contacts between the chromophore and the surrounding protein barrel. Here we review our current knowledge of blue, green, and red chromophore formation in permanently emitting FPs, photoactivatable FPs, and fluorescent timers. Progress in understanding the interplay between FP structure and function has allowed the engineering of FPs with many desirable features, and enabled recent advances in microscopy techniques such as super-resolution imaging of single molecules, imaging of protein dynamics, photochromic FRET, deep-tissue imaging, and multicolor two-photon microscopy in live animals.
