蛋白质的结构状态包括有序的球状结构域以及以高度灵活的构象集合孤立存在的内在无序的蛋白质区域。已经开发了各种计算工具来基于氨基酸序列区分有序和无序片段。然而，IDR的性质也可能取决于各种条件，包括与球状蛋白伴侣或环境因素（如氧化还原电位）的结合。这些情况提供了进一步的挑战，无序段的计算表征。在这项工作中，我们提出了IUPred2A，一个组合的网络接口，允许生成基于能量估计的预测有序和无序的残基IUPred2和无序的结合区域由ANCHOR 2。更新后的Web服务器保留了原始程序的健壮性，但提供了几个新功能。虽然IUPred仅实施了小错误修复，但下一版本的锚通过针对新数据集优化的新架构和参数进行了显着改进。此外，氧化还原敏感区域也可以通过一个新的实验功能突出显示。Web服务器提供图形和文本输出、RESTful界面、软件下载访问和广泛的帮助，并且可以在新的位置访问：http://iupred2a.elte.hu。
The structural states of proteins include ordered globular domains as well as intrinsically disordered protein regions that exist as highly flexible conformational ensembles in isolation. Various computational tools have been developed to discriminate ordered and disordered segments based on the amino acid sequence. However, properties of IDRs can also depend on various conditions, including binding to globular protein partners or environmental factors, such as redox potential. These cases provide further challenges for the computational characterization of disordered segments. In this work we present IUPred2A, a combined web interface that allows to generate energy estimation based predictions for ordered and disordered residues by IUPred2 and for disordered binding regions by ANCHOR2. The updated web server retains the robustness of the original programs but offers several new features. While only minor bug fixes are implemented for IUPred, the next version of ANCHOR is significantly improved through a new architecture and parameters optimized on novel datasets. In addition, redox-sensitive regions can also be highlighted through a novel experimental feature. The web server offers graphical and text outputs, a RESTful interface, access to software download and extensive help, and can be accessed at a new location: http://iupred2a.elte.hu.
