Overview

Rhea is an expert-curated knowledgebase of chemical and transport reactions of biological interest and the standard for enzyme and transporter annotation in UniProtKB. Rhea uses the chemical dictionary ChEBI (Chemical Entities of Biological Interest) to describe reaction participants. Rhea provides computationally tractable enzyme annotations in UniProtKB that support chemical ontology and structure based searches in the UniProt website, REST API, and SPARQL endpoint. Rhea also provides reaction data for a host of other resources including ChEBI, MetaboLights, Reactome, and The Gene Ontology, which now bases enzyme molecular functions on Rhea. Rhea and UniProtKB are SIB resources; they are listed in Expasy, the Swiss Bioinformatics Portal.

The goal of this course is to provide basic theoretical and practical knowledge that will enable participants to mine enzyme data in UniProtKB using chemical structure data and chemical classifications from Rhea and ChEBI.

Audience

This course is addressed to biologists, bioinformaticians, cheminformaticians, programmers and data scientists working with enzyme and small molecule data, including those working with metabolomics data and metabolic networks.

Learning outcomes

At the end of the course, the participants are expected to:
* have acquired a good understanding of the structure and design of the chemical ontology ChEBI and the reaction knowledgebase Rhea, and how they are used in UniProtKB annotation
* be able to search UniProtKB and Rhea using chemical ontology terms and chemical structures - including exact chemical structure searches, as well as substructure and similarity searches, using interactive and programmatic means (REST API and SPARQL).
* have acquired a basic understanding of how to use RDF and SPARQL for integration of chemical and biological data in UniProt with other key knowledgebases and data repositories providing RDF and SPARQL endpoints.
