中药蛋白不仅具有一定的营养价值和生物活性,作为药效成分生源合成途径中的关键酶在中药中的作用也是至关重要的.它们通过调控生物合成途径、选择性合成、控制药物质量和稳定性等方面,对中药的药效成分合成起着不可忽视的作用.近年来,利用各种方法和技术对蛋白质的结构与功能进行研究取得了很大的进展.然而,对中药蛋白质结构与功能的研究相对滞后.因此,迫切需要借助现代科学技术手段研究中药蛋白质结构及其功能,以促进中药蛋白创新药物的发现和药效成分生源合成途径的阐明.该文着重介绍蛋白质结构鉴定和功能研究的最新技术,主要针对蛋白质结构鉴定技术,包括光谱法、质谱、核磁共振、X射线晶体衍射、显微镜技术、结构预测等;同时还介绍了蛋白功能研究的方法,包括液质联用、免疫共沉淀、酵母双杂交、下拉实验等.通过系统梳理这些技术和方法,为中药蛋白质结构鉴定和功能研究提供策略和技术层次的参考,以期推动中药蛋白质结构和功能的深入探索.
Methods for research on structures and functions of traditional Chinese medicine proteins
Traditional Chinese medicine proteins(TCMPs)not only have nutritional values and biological activities but also serve as key enzymes in the synthesis of pharmacodynamic components in traditional Chinese medicines.They play a role in the synthesis of pharmacodynamic components by regulating biosynthesis and selective synthesis pathways and controlling drug quality and stability.The recent years have witnessed great progress in the research on the structures and functions of proteins using various methods and technologies.However,the research on the structures and functions of TCMPs lags behind.Therefore,it is urgent to study the structures and functions of TCMPs using modern means to promote the discovery of innovative drugs based on TCMPs and clarify the synthesis pathways of pharmacodynamic components.This study introduces the latest techniques for studying protein structures and functions,including spectroscopy,mass spectrometry,nuclear magnetic resonance,X-ray crystal diffraction,microscopy,and structure prediction.Furthermore,this paper introduces the methods for protein functional studies,including liquid chromatography-mass spectrometry,co-immunoprecipitation,yeast two-hybrid,and pull-down assay.By systematically reviewing these techniques and methods,this paper provides technical references for the structural identification and functional studies of TCMPs,with the aim of promoting the in-depth exploration of the structures and functions of TCMPs.
