ABSTRACT Fluorescent GTP analogues are utilized for an assortment of nucleic acid and protein characterization studies. Non-hydrolysable analogues such as GTPγS offer the advantage of keeping proteins in a GTP-bound conformation due to their resistance to hydrolysis into GDP. Two novel fluorescent GTPγS molecules were developed by linking fluorescein and tetramethylrhodamine to the γ-thiophosphate
摘要 荧光 GTP 类似物用于各种核酸和蛋白质表征研究。不可水解的类似物(例如 GTPγS)具有将蛋白质保持在 GTP 结合构象的优势,因为它们能够抵抗水解为 GDP。通过将荧光素和四甲基罗丹明连接到 GTPγS 的 γ-硫代磷酸盐,开发了两种新型荧光 GTPγS 分子。对这两种化合物的化学和生物学分析揭示了它们的成功合成和与微管蛋白核苷酸结合位点结合的能力。这两种新的荧光不可水解核苷酸为 GTP 结合蛋白的生物物理和生化表征提供了新的可能性。
