摘要:

虽然有许多关于蛋白质结构,分子模拟,热力学和生物信息学方法的好教科书,但在结构生物信息学领域没有好的入门级书籍。这本书的目的是给一个结构生物信息学,这是以前的主题满足通过计算分析探索三维蛋白质结构的介绍。我们提供了现有的计算技术的概述,验证,模拟,预测和分析蛋白质结构。更重要的是,它旨在提供关于如何以及何时使用这些技术的实用知识。我们将从三个主要的优势点考虑蛋白质:蛋白质结构定量,蛋白质结构预测,蛋白质模拟和动力学。这项工作的主要重点是提供一个蛋白质结构测定的实验技术的背景。重点是X射线晶体学和核磁共振光谱(NMR),这是迄今为止用于确定可溶性蛋白质结构的主要方法。我们还将介绍低温电子显微镜(cryo-EM)和电子衍射,它们更适合于分析膜蛋白和较大的蛋白质复合物。最后,总结了更多的定性技术,用于获得对蛋白质的整体结构和动力学的洞察。请注意,这篇蛋白质结构测定的介绍旨在让读者熟悉不同的实验技术,它们的优点和瓶颈,但对这一概念的全面数学和技术描述超出了本文的范围。

英文摘要:

While many good textbooks are available on Protein Structure, Molecular Simulations, Thermodynamics and Bioinformatics methods in general, there is no good introductory level book for the field of Structural Bioinformatics. This book aims to give an introduction into Structural Bioinformatics, which is where the previous topics meet to explore three dimensional protein structures through computational analysis. We provide an overview of existing computational techniques, to validate, simulate, predict and analyse protein structures. More importantly, it will aim to provide practical knowledge about how and when to use such techniques. We will consider proteins from three major vantage points: Protein structure quantification, Protein structure prediction, and Protein simulation & dynamics. The main emphasis of this work is to provide a background on experimental techniques for protein structure determination. The focus is set on X-ray crystallography and Nuclear Magnetic Resonance spectroscopy (NMR), which are by far the main methods used to determine the structure of soluble proteins. We will also introduce cryogenic Electron Microscopy (cryo-EM) and electron diffraction which are more suited to analyze membrane proteins and larger protein complexes. At the end, more qualitative techniques are summarized that are used to obtain insight on the overall structure and dynamics of proteins. Note that this introduction to protein structure determination aims at familiarizing the reader to different experimental techniques, their benefits and bottlenecks, but that a thorough mathematical and technical description of the concept is beyond the scope of this work.
