OrganiZymeDB 发布：收录 28,121 条酶有机溶剂稳定性与功能实验数据
OrganiZymeDB: a comprehensive database of enzyme stability and function in the presence of organic solvents
OrganiZymeDB 是一个经人工整理的综合数据库，收录了 28,121 条酶在有机溶剂存在下的稳定性与功能实验测量数据，来自 646 篇文献、覆盖 704 种不同蛋白。该数据库针对的是工业生物催化中有机溶剂耐受性数据长期缺乏公共资源的问题。每条记录都注释了实验条件，包括测定类型、溶剂种类与体积分数、测定溶液组成、pH、温度、底物、产物和酶制备方法，并附有蛋白三维结构及与其他数据库的交叉链接。作者表示，该数据库既方便实验人员查询目标酶的溶剂兼容性数据，也为计算研究者开发和评估酶溶剂耐受性预测方法提供了整理好的数据集，最终服务于稳健工业生物催化剂的设计。

Low enzymatic tolerance to organic solvents is a major bottleneck for the development of industrial biocatalysis, since many substrates have limited water solubility, thus requiring the use of organic solvents for substrate solubilization and process economic viability. Yet, despite decades of experimental research in this field, no public resource currently exists that systematically collects and curates these data, limiting their accessibility and reuse for large-scale analyses and for the development and validation of computational methods. To address this gap, we present OrganiZymeDB (https://organizymedb.org/), a comprehensive, manually curated database of 28,121 experimental measurements of enzyme stability and function in the presence of organic solvents, compiled from 646 publications and covering 704 distinct proteins. Each entry is extensively annotated with the experimental conditions, including assay type, solvent identity and volume fraction, assay solution composition, pH, temperature, substrate(s), product(s), and enzyme production method, as well as the protein 3D structure and cross-links to other databases. OrganiZymeDB will assist both experimentalists, by providing straightforward access to solvent-compatibility data for enzymes of interest, and computational scientists, by providing a well-curated dataset to develop and evaluate methods for predicting enzyme solvent tolerance, ultimately enabling the design of robust industrial biocatalysts.
