Abstract

Amyloids and their infectious subset, prions, represent fibrillary aggregates with regular structure. They are formed by proteins that are soluble in their normal state. In amyloid form, all or part of the polypeptide sequence of the protein is resistant to treatment with proteinase K (PK). Amyloids can have structural variants, which can be distinguished by the patterns of their digestion by PK. In this review, we describe and compare studies of the resistant cores of various amyloids from different organisms. These data provide insight into the fine structure of amyloids and their variants as well as raise interesting questions, such as those concerning the differences between amyloids obtained ex vivo and in vitro, as well as the manner in which folding of one region of the amyloid can affect other regions.

朊病毒和淀粉样蛋白的蛋白酶K抗性核心。
淀粉样蛋白及其传染性亚群朊病毒是结构规则的原纤维聚集体。它们是由正常状态下可溶的蛋白质形成的。在淀粉样蛋白形式中,蛋白质的全部或部分多肽序列对蛋白酶K (PK)的处理具有抗性。淀粉样蛋白可以有结构变异,这可以通过它们被PK消化的模式来区分。在这篇综述中,我们描述并比较了来自不同生物的各种淀粉样蛋白的抗性核心的研究。这些数据提供了对淀粉样蛋白及其变体的精细结构的深入了解,同时也提出了一些有趣的问题,例如关于在体外和体外获得的淀粉样蛋白之间的差异,以及淀粉样蛋白一个区域的折叠可以影响其他区域的方式。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
