Abstract

The formation of disulfide bonds is critical to the folding of many extracytoplasmic proteins in all domains of life. With the discovery in the early 1990s that disulfide bond formation is catalyzed by enzymes, the field of oxidative folding of proteins was born. Escherichia coli played a central role as a model organism for the elucidation of the disulfide bond-forming machinery. Since then, many of the enzymatic players and their mechanisms of forming, breaking, and shuffling disulfide bonds have become understood in greater detail. This article summarizes the discoveries of the past 3 decades, focusing on disulfide bond formation in the periplasm of the model prokaryotic host E. coli.

大肠杆菌胞浆中二硫键的形成。
二硫键的形成对于生命各领域中许多细胞质外蛋白质的折叠至关重要。20 世纪 90 年代初,随着人们发现二硫键的形成是由酶催化的,蛋白质氧化折叠领域应运而生。大肠杆菌作为阐明二硫键形成机制的模式生物发挥了核心作用。从那时起,人们对许多酶的作用及其形成、断裂和重组二硫键的机制有了更详细的了解。本文总结了过去 30 年的发现,重点介绍了模式原核宿主大肠杆菌外质中二硫键的形成。

期刊介绍: EcoSal Plus is the authoritative online review journal that publishes an ever-growing body of expert reviews covering virtually all aspects of E. coli, Salmonella, and other members of the family Enterobacteriaceae and their use as model microbes for biological explorations. This journal is intended primarily for the research community as a comprehensive and continuously updated archive of the entire corpus of knowledge about the enteric bacterial cell. Thoughtful reviews focus on physiology, metabolism, genetics, pathogenesis, ecology, genomics, systems biology, and history E. coli and its relatives. These provide the integrated background needed for most microbiology investigations and are essential reading for research scientists. Articles contain links to E. coli K12 genes on the EcoCyc database site and are available as downloadable PDF files. Images and tables are downloadable to PowerPoint files.
