具有生物价值的化学实体 (ChEBI) 是免费提供的分子实体词典,重点关注“小”化合物。所讨论的分子实体要么是天然产物,要么是用于干预生物体过程的合成产品。基因组编码的大分子(核酸、蛋白质和通过裂解从蛋白质衍生的肽)通常不包括在 ChEBI 中。除了分子实体之外,ChEBI 还包含实体组(分子实体的一部分)和实体类。 ChEBI 包括本体论分类,其中指定了分子实体或实体类别与其父代和/或子代之间的关系。 ChEBI 可在线获取:http://www.ebi.ac.uk/chebi/。本文报告了自 2007 年上次 NAR 报告以来 ChEBI 的新功能,包括子结构和相似性搜索、社区创作 ChEBI 数据集的提交工具以及 ChEBI 中存储的化学结构数量增加了 30 倍。
Chemical Entities of Biological Interest (ChEBI) is a freely available dictionary of molecular entities focused on ‘small’ chemical compounds. The molecular entities in question are either natural products or synthetic products used to intervene in the processes of living organisms. Genome-encoded macromolecules (nucleic acids, proteins and peptides derived from proteins by cleavage) are not as a rule included in ChEBI. In addition to molecular entities, ChEBI contains groups (parts of molecular entities) and classes of entities. ChEBI includes an ontological classification, whereby the relationships between molecular entities or classes of entities and their parents and/or children are specified. ChEBI is available online at http://www.ebi.ac.uk/chebi/. This article reports on new features in ChEBI since the last NAR report in 2007, including substructure and similarity searching, a submission tool for authoring of ChEBI datasets by the community and a 30-fold increase in the number of chemical structures stored in ChEBI.
