Saccharomyces cerevisiae Pathway/Genome Database

Image of Saccharomyces cerevisiae organism

YeastCyc is a Pathway/Genome Database of the model eukaryote Saccharomyces cerevisiae S288c. In addition to genomic information, the database contains metabolic pathway, reaction, enzyme, and compound information, which has been manually curated from the scientific literature. The curation process includes periodic updates to the metabolites, reactions and pathways from the current version of MetaCyc to ensure compatibility with other members of the MetaCyc family of databases. YeastCyc has been curated from 47,000 publications. For details on recent curation, please click here.

This site includes extensive retrieval, visualization and analysis tools, including a genome browser and a metabolic map diagram. There are tools for analysis of gene expression, metabolomics and ChIP-chip data. You can search and align sequences for Saccharomyces cerevisiae and other microbial genomes and perform comparative analysis. You can store groups of genes and pathways into a SmartTable, and then browse, analyze and share with other users.
